Brake bias is the balance of braking power between the front and rear brakes. It is usually represented as a percentage. For example, a brake bias of 75/25 means that the front brakes get 75% of the braking power, and the rear brakes get 25% of the braking power. Brake bias controls the way that the car handles when the brakes are applied. Therefore, it is useful in changing the corner entry handling characteristics of a car if braking is necessary going into a corner. Moving the brake bias toward the front brakes makes the car tighter and more stable while braking and entering a turn. Moving the brake bias toward the rear makes the car looser while braking and entering a turn.

The front brakes should always have more braking power than the rear because the weight transfer during braking loads the front tires and unloads the rear tires. If you have too much rear brake, the rear tires will lock as weight transfers forward and makes the rear of the car lighter. However, make sure you do not have too much front brake either. Excessive front braking power can lock up the front tires and decrease the overall effectiveness of your brakes since you are not using the rear tires to slow down the car. As a starting point, try setting your brake bias between 70/30 and 80/20. Fine-tune the car from there.

Production cars do not have a brake bias adjustment. Adding a brake bias adjustment often requires modifications to your car’s brake system. A dual master cylinder setup is necessary to separately control the front and rear brakes. If you plan to use your car mostly for street driving, a mild aftermarket brake upgrade will suffice for improving your braking performance. However, if you will be racing, aftermarket brakes with a brake bias adjuster will be a valuable addition in making your car perform well on the track.

Optimizing the Aerodynamic Balance of your Car

Optimizing the Aerodynamic Balance of your Car

Aerodynamics can be used to control the handling of a car in high-speed corners (greater than approximately 60 mph). Aerodynamic components push down on the car, or create downforce, which helps the tires maintain better traction. The two main aerodynamic upgrades are front bumpers and rear wings. While these two components can increase cornering speeds when installed on your car, they will also increase drag and limit your top speed.

Aerodynamic components should only be used to tune high speed cornering characteristics. They will have little or no effect on low-speed handling. Additionally, aerodynamics should be relied upon to increase the overall grip of your car. It should not be used to correct severe understeer or oversteer. Try to rely upon mechanical suspension tuning to control understeer/oversteer. Only turn to aerodynamics as a last resort. This is because aerodynamic grip cannot always be relied upon in a racing situation. For instance, if you are closely following another car, there will be less air flowing over your car because the car in front is breaking through the air for you. The reduced airflow (and therefore downforce) on your car will cause you to lose grip. If you rely heavily on aerodynamics to improve handling, your car will become difficult to drive when you are in close proximity with other cars.

Aerodynamic components work by deflecting air in a way to create a downward force on the car. Air hits the car at an angle, which pushes the car into the ground. At the same time, the air gets deflected up and over the car. Aggressively sloped front bumpers and large wings will generally create more downforce than small wings and mild front bumpers.

Usually, it is not possible to adjust the amount of front downforce without changing your front bumper. However, wings often have inserts and angle adjustments that can be used to change rear downforce. By increasing wing angle or adding wing inserts, you increase downforce on the rear of the car. This pushes the rear wheels more firmly into the ground and prevents them from slipping. Oversteer can be corrected in this way. If your car understeers in high-speed corners, you can reduce the angle of the wing or take out wing inserts to reduce rear downforce and correct the understeer. Keep in mind that adding downforce will help you increase your cornering speeds but will lower your top speed due to the extra drag. Still, you will usually want to maximize the downforce because the majority of road courses do not have very long straights. On a track with long straights, reducing downforce (and therefore drag) may improve your lap times.

Wow! 250 MPH in a car

Wow! 250 MPH in a car

by: Paul Cooper

250 mph Supercar: Bugatti Veyron 16.4
250 mph Supercar: Bugatti Veyron 16.4 © M 93 / Wikimedia Commons, via Wikimedia Commons

Is this crazy? Or does it make sense? Bugatti, a small car company bankrolled by Volkswagen (VW), has brought out the Veyron 16.4 with a top speed of 248 mph – and the car was tested at the speed on the fastest track Volkswagen could find in Europe!

Nowhere else would allow the car to get to that speed and be timed for long enough to say it actually could do this. The previous record for a production car was 242 mph round the Nardo track in Italy – and that required a great deal of skill by the driver to keep the car on the banked track!

This sort of speed – and the power to get there – are pretty much off the planet, but since then, other companies – with a fraction of the resources of Bugatti – have decided they should aim for 250 mph. ‘What for?’, you might ask. I guess it is a bit like saying the moon is there so let’s go there.

W-16, 1,001 bhp engine

Bugatti Veyron 16.4 Supercar

The Bugatti Veyron is a very impressive car, powered by a W-16-cylinder 8.0 liter engine developing 1,001 bhp. The ‘4’ stands for the four turbochargers needed to boost the engine to that amount of power. The whole Bugatti project was the idea of Dr Ferdinand Piech, then chairman of the VW Group. He wanted VW to build a car to showcase technology and to move the goal posts so no one could get close. Evidently, during testing this engine was proved to be reliable when producing 1,200 bhp.The car does showcase technology. The engine is similar to the W-12 installed in the Audi A8 and S8, and in turbocharged form in the Bentley Continental GT and Flying Spur.The gearbox is also based on VW Group technology. It is a seven-speed sequential box with automatic or manual shifting. It has a dual clutch arrangement so that when you change gear the power continues to be transmitted all the time, one clutch disengaging exactly at the moment the other engages. Stunning technology that really delivers benefits.The same concept is available in six-speed form in the VW Golf, Audi A3 and S3. It is called DSG. Of course, the Bugatti has a special version of this concept, made by Ricardo, a powertrain specialist in the UK.

The Bugatti has a carbon fiber structure, suspension like a racing car, and two large air intakes in the roof to keep that huge engine cool. Of course, the engine is mounted behind the driver and passenger but forward of the rear wheels.

Most exotic cars have rear-wheel drive, but the Bugatti Veyron 16.4 has so much power that it has four-wheel drive. Actually, some Audis, including the 450 bhp RS4, and all Lamborghinis – also in the VW Group – now have four-wheel drive. Again, the Bugatti is showcasing group technology

If you are wondering why four-wheel drive is needed, just think about it. With two-wheel drive there would be 500 bhp going through each tire! Most makers of supercars and exotic cars think that 300 bhp per tire is plenty.Ok, so the Bugatti was timed at 248 mph, and reaches 60 mph in less than 3 seconds. Did the other makers of exotic cars give up, and say: ‘Well, we can’t match that’?No, Pagani, produced the 650 bhp Zonda F with an option of 700 bhp. Saleen upped the power output of its S7 to 750 bhp, while Ferrari produced a few FXXs with 850 bhp, and Maserati also has a version of the MC-12 developing 750 bhp or so.On the other hand Koenigsegg decided not to pursue the power race for the time being at least. After all its CCR has a 806 bhp engine, and was timed at 242 mph. Instead, Koenigsegg has introduced the CCX which is designed to meet US regulations and is a more practical street machine.

Others have decided to go for maximum power including one of the tuners of Porsche 911s. Then, a small British company is introducing a car with a turbocharged 7.0 liter V-8 with a power output of 1,000 bhp. They say that the engine could be tuned to 1,200 bhp.

More will follow down this route to madness. Me? I’d go for the 500 -600 bhp myself in a car that really handles and is very, very responsive. Like a Pagani Zonda or an Ascari KZ1.

The hottest supercars are mid-engined

The hottest supercars are mid-engined

The hottest supercars are mid-engined: Ferrari F430

For ultimate performance, the mid-engined layout is used for supercars – just like it is on racing cars. Typical mid-engined supercars are the Ferrari F430, Lamborghini Murcielago and Noble M400. Mostexotic supercars are also mid-engined.

The mid-engined layout has these advantages over front-engined cars:

There is more weight over the rear wheels, but not too much, so traction is good
Because the driver sits in front of the engine, the car can be lower, reducing frontal area and the center of gravity. That means a higher top speed and better cornering.
Aerodynamics of mid-engined cars are usually the best
Because there is no propeller shaft taking the drive from the front to the back, mid-engined cars are usually lighter than front-engined cars

Those add up to a big advantage in performance. These cars are usually powered by V-type engines, or boxer engines, as these are lower and take up less room than in-line engines.

Gearbox usually behind the rear axle

To get the weight well back, the gearbox is usually mounted behind the rear axle gears as a transaxle. The weight distribution is about 42% front to 58% rear to 39% front to 61% rear. Any more weight at the back upsets the handling balance.Because the weight of a mid-engined car is concentrated at the middle, there is less force tending to spin the car when it corners than a front-engined car, which is more like a dumbbell. But, things happen faster with a mid-engined car! If you upset the balance badly when cornering, the car can spin very quickly.

To get the power onto the road, the rear tires are wider than the front ones on a mid-engined car – usually about 30% wider. The wider rear tires also make the cars more stable at high speeds.

Used on racing cars first

The mid-engined layout was adopted first for single-seater racing cars, and then for sports racing cars before being adopted for road cars.Ferrari and Lamborghini have been making mid-engined supercars for many years, and many smaller companies make mid-engined cars as well. The cheaper supercars usually have front engines, and are more like ordinary cars – except in their performance.

Lola GT a trend-setter

One of the first mid-engined sports racing coupes was the Lola GT, which was ahead of its time with a monocoque body – that is the body panels formed the structure. Its competitors, like the Ferrari Testarossa, all had tubular frames, which were heavier and not so stiff. It became the model for the Ford GT40 racing cars, and later this layout became popular for supercars.The advanced structure of the GT40 helped Ford beat Ferrari at Le Mans and in other long distance races. Now, you can buy a Ford GT supercar, similar in looks to the GT40, but bang up to date.

What about rear-engined cars like the Porsche 911? Rear-engined cars have the engine behind the rear wheels, so there is a lot of weight on the rear wheels. Also, because the engine sticks out behind, when the car starts to slide, the mass of the engine keeps it going. This is not the best layout, although it makes quite a practical 2+2.

Maserati MC12 A Winner

Maserati MC12 A Winner

by: John Hartley

Maserati MC12
Maserati MC12 image By No machine-readable author provided. Jbattersby assumed (based on copyright claims). [Public domain], via Wikimedia Commons

Designed to win races, the Maserati MC12 is actually sold as a road car, albeit it a very impractical one. Still what do you expect with a 620 bhp exotic car? The car looks just like the sports racing car that it is. To be fair, it is a real two-seater while the cars that race at Le Mans are more like single-seaters.

Only 25 MC12s were built initially, and quite a few were used for racing. Actually, when they heard about Maserati building the MC12 for the GTA championship (ooops, sorry for sale as a road car, was the official line, I think) some of the other companies threatened to withdraw as they thought the presence of the MC12 on the starting grid would make a farce of the whole series.

Although the Maserati MC12, is a true exotic car, it is based on the Ferrari Enzo. The whole idea was to upgrade Maserati’s image following a checkered history. The glory of the 50s, when Maserati was a regular winner of Grand Prix, got lost in the mire of an economic downturn, when the company took the wrong turn more than once.

As Ferrari and Maserati are both part of the Fiat Group, and were in fact in the same sub-group, it made sense to modify the Enzo to get Maserati back as a winner. Now, Ferrari and Maserati have been put in different sub-groups, so this sort of collaboration is not expected in the future.

V-12 from Ferrari with 622 bhp

Blue Maserati MC12 Corsa

The Maserati MC12 looks completeley different from the Enzo, though,, with a long nose and very long tail. Where the Enzo is angular, the MC12 is curved. It has a carbon fiber body structure with steel sub-frames front and rear. Power comes from a 6.0 liter V-12 developing 622 bhp @ 7,500 rpm, and 480 lb ft (652 Nm) torque @ 5,500 rpm. A semi-racing engine to be sure. It is coupled to a semi-automatic six-speed sequential gearbox, developed by Ferrari in racing.
Suspension is by double wishbones, with inboard spring and damper units acting through pushrods. These are mounted horizontally as on the Enzo. The dampers have variable rates. Quite a car, but not as extreme as the Bugatti Veyron or the latest Saleen S7.

Following the racing success of the MC12, Maserati is now to build a more extreme version – the MC12 Corsa. The MC12 Corsa has a massively uprated Enzo V-12 engine giving about 750bhp. You can get this for about $1.3 million – or £700,000 or Euros 1 million depending where you live.

But this is not a road car, nor will you be able to race it in any official categories – so this is a trackday special at a huge price. Maserati plans to build about 12 MC12 Corsas a year.

Porsche Caymen S

Porsche Caymen S

by: Wayne Treister

Porsche Cayman S

If you are knew to the world of Porsche and haven’t been keeping up with the Porsche changes the Porsche Caymen S is basically a Boxter with a hatchback and a steel coupe roof.

But wait there’s a little more to it. The Cayman has a stiffer set of springs for the strut suspension, thicker anti-roll bars, and it comes standard with 18 inch wheels.

The Caymen uses the familiar 3.4 liter engine seen in the Porsche M96, Boxter, and 911. Of course it’s been tweaked and now it delivers a whopping 295 HP and 255 pound foot of torque. The old Boxter version had only 280 HP and 236 lb-ft to offer.

From 0 to 60 is capable in 5.1 seconds you’ll find your top speed at 171 MPH. That’s all the speed you’ll ever need. The PSM or Porsche Stability Management System is standard equipment on the Caymen. And the Sport Chrono package with built in lap time counter will be optional.

Another option is ceramic brakes. If you aren’t familiar with ceramic brakes you should be. These brakes are half the weight of stand cast iron brakes. You get exceptional braking power, less heat fade, and low brake dust. They Cayman brakes are identical to the Boxter’s with just a little more air cooling and ABS tweaking.

A look at the exterior and you will instantly know that the body is built off the Boxter platform. In fact many of the body panels are interchangeable. The rear windows are the same shape as the 911 if you were to turn them on end.

Porsche Cayman S

The Cayman has a rapidly sloping hatch that drops quickly and deeply and it is accented with a scripted Cayman S on the rear wing which deploys at speeds over 75 MPH.The hatch is a nice light weight which rises with no effort presenting you with a nice size trunk that is a decent depth. It’s very similar to the Boxter trunk.And there was some smart design thinking here. An aluminum scuff plate covers the area from trunk up to the cargo shelf. There are also two narrow storage bins and there is plenty of useable floor space.

If you are familiar with the Boxter when you park yourself in the driver’s seat you’ll instantly feel like your back in the Boxter except that the instrument faces are gray and the cargo shelf is behind your head. So are you ready to take it for a cruise?

First thing you’ll notice is that the Caymen fits both driver and passenger snuggly. You’ll notice the night tight suspension and how the car hugs the road never missing a beat. It’s impressively intuitive as long as you don’t mess up.

Porsche Cayman S

The steering puts you in complete control with the blacktop and its responsible and sensitive to your every mood. Drive it neatly and it will never let you down. Know your car and how to drive and it will be hard to be outperformed.First impressions are that the Cayman is as snug-fitting for the driver as it was for the passenger and that the mid-mounted engine makes life hard for the air-conditioning; the cabin serves up rump roast over frozen heart as a summer dish.

The chassis has been seriously beefed up and is more of a partner than ever before. Combine that with the Michelin tires that have amazing gripping you are going to have a ride like nothing you’ve experienced before.

The new Caymen is everything the 911 has always been and more. It’s not only a great ride on the street it’s also a great track ride. It sounds great, looks great, and performs great. But then after all it’s a Porsche and would you accept anything less? If there were awards for best car this one would certainly be in the running.

If you haven’t checked out the Porsche Caymen be sure you do!

Freestream: A Small Sports Car That Out-Accelerates The Biggest And Best

Freestream: A Small Sports Car That Out-Accelerates The Biggest And Best

by: John Hartley

Caparo Sports Car: Caparo T1

Latest super-sports car from England is the Caparo Freestream supercar, which will have a power-to-weight ratio of 1,000 bhp per ton! The Bugatti Veyron which has 1,001 bhp manages about 560 bhp per tonne, so how you can see that the Caparo is streets ahead of any other supercar in power-to-weight ratio, and that is what makes cars accelerate fast. And fast acceleration is very exciting, and can also improve safety of the car in some circumstances.

So how does the Caparo do it? Not with 2,000 bhp because the car would weigh at least 2.5 tons, which would miss the target. In fact, Bugatti has demonstrated that sheer power means a lot of weight, particularly in the transmission and brakes.

To get a high power-to-weight-ratio you need a light car. And why is a high power-to-weight-ratio important? Because it dictates how fast the car accelerates flat out. A car with a high power-to-weight-ratio can cover the ground quicker because it gets out of corners fast and accelerates up the straights faster. So long as the handling is good, the car will be very fast anywhere.

Lightweight solution

Instead of going for a big engine with masses of power, the designers, who worked on the McLaren F1, have gone for ultra lightweight and a compact V-8 engine based on F1 technology. The result is a pencil-slim car with 480 bhp at 10,500 rpm from a supercharged 2.4 liter engine, and a weight of under 1,100 lb. Both the new engine and transmission are very light, as are all the components. The very narrow body without fully enclosed fenders also reduces weight.

The whole design concept has been aimed at reducing weight, ore not putting in things that add weight. First, the power train is very light compared with mass-production units. Then, the carbon fiber body/chassis is also much lighter than most, as designers without Grand Prix experience tend to over-design their structures. Also, because the power train is light, the loads on the body are lower, so again less weight does not need to be built into the structure.

It has a very narrow cockpit, with the passenger sitting slightly behind the driver to reduce width, so this is more of a track racer or trackday special than a road car. Even so, this car changes the concept of exotic cars to where it should be – ultra-lightweight, compactness and exciting performance round twisty roads or circuits.

To save weight they have adopted a narrow coupe body with cycle-type front mudguards, and side-mounted radiators which flow into the rear fenders.

In fact, these are all factors used by Colin Chapman to design the early Lotus cars, and since used by all racing car companies. In other words, the Caparo Freestream really takes advantage of Grand Prix technology to build a supercar.

The Caparo Freestream looks very unusual, but if you want sheer performance this is it! The makers say the car will hit 200 mph, and accelerate from a standing start of 100 mph in 5.5 seconds!! Holy mackerel that is fast. Oh, and they also say that owing to the downforce available, the T1 will be able to corner and brake at 3g – incredible. This tremendous cornering power and braking would not be possible without the use of Grand Prix design principles.

On top of all that, Caparo, which produces a lot of components for the auto industry, have priced the Freestream at about $320,000 (£176,000).

8 Facts You Must Know About Lamborghini

8 Facts You Must Know About Lamborghini

8 Facts You Must Know About Lamborghini: 1963 Lamborghini 350 GTV
1963 Lamborghini 350 GTV image By Craig Howell from San Carlos, CA, USA; (cropped and adjusted by uploader Mr.choppers) (Lamborghini 350 GTV) [CC BY 2.0 (http://creativecommons.org/licenses/by/2.0)], via Wikimedia Commons

Lamborghini, or Automobili Lamborghini S.p.A. as it’s officially called, produces some of the most exciting sports cars in the word. Some of the newer Lamborghini models are the Countach, the Diablo, the Gallardo and the Murcielago.

Fact 1: Lamborghini is named after the founder of the company Ferruccio Lamborghini (1916-1993). Ferruccio Lamborghini founded the company in 1963 when he was 47 years old. The factory is located in a small Italian village called Sant’Agata Bolognese near Bologna.

Fact 2: Ferruccio Lamborghini was a successful tractor manufacturer before he got interested in sports cars. His interest in sports cars made him buy many different high-performance cars including both Maseratis and Ferraris, but he was never really happy with any of them and therefore decided to built his own, perfect sports car,

Fact 3: Lamborghini used to be an independent company, but today it is a subsidiary of the German company Audi AG. Audi AG became the owner of Lamborghini in 1998. Lamborghini went bankrupt in 1978 and was sold to Chrysler a long time before Audi AG became the sole owner of the company.

Fact 4: The fastest Lamborghini is the Le Mans version of the Murcielago R-GT model. It has been reported to have a top speed of 370 km/h. The fastest street model from Lamborghini is the Murcielago LP640 with an estimated top speed of 340 km/h. Both of the models have a V12 engine with more than 6000 cc.

Fact 5: Several of the newer Lamborghini models feature the familiar Lamborghini scissor doors that rotate up and forward on a hinge near the front of the door. The Countach, the Diablo and the Murcielago all have scissor doors, but the Gallardo does not. Both the Countach and the Diablo are no longer being produced, so the Murcielago is the only current model with scissor doors.

Fact 6: No Lamborghini have ever been produced with less than a V8 engine. Most of the Lamborghini models throughout the history of the company have come with the legendary Lamborghini V12 engine, but the newest model, Gallardo, only have a V10 engine. No Lamborghini models with a V8 engine have been since production of the Silhouette stopped in 1989.

Fact 7: The first Lamborghini was the 350GTV from 1963. It was extremely fast for its time with a top speed of 280 km/h. In 1964 a smaller version of the 350GTV appeared. The smaller version was called 350GT and had a top speed of 240 km/h. The Countach from 1974 was the first Lamborghini to go faster than 300 km/h.

Fact 8: In 1975 did Walter Wolf, a rich Canadian businessman and F1 racing team owner, persuade Lamborghini to produce three super powered Countach models. The Wolf Countach had the same engine as the orginal Countach prototype and were able to reach a top speed of 315 km/h.

A Brief History Of Porsche

A Brief History Of Porsche

A Brief History Of Porsche: 1954 Porsche 356 1500 Super

Ferdinand Porsche was an automobile engineer with more than a thousand patents to his name, and played an important role in the development of airplanes and the construction of tanks for the Wehrmacht as well. In the 1920s he was appointed chief engineer at Mercedes-Benz in Stuttgart and later set up his own engineering workshop. There he designed, among other things, the Volkswagen. He acted as chief of operations at the plant where the Volkswagen was made, Wolfsburg, and at the end of the war he was interned by the Allies.

He was released a few years later and immediately went to work building his first car with his son, Ferry Porsche. This car was named the Porsche 356, after Ferry, and was a sports car with styling reminiscent of the Volkswagen. In fact it had the same four-cylinder boxer engine, and wore it rear-mounted, just as the VW did. This meant that it was far from being a powerful sports car, boasting a mere 40 bhp and a maximum speed of 87 mph (140 km/h). Distinguished by its elegant and innovative body, the Porsche 356 was first produced as a convertible and then as a hard top. Father and son developed it in the workshop of Erwin Komenda, a master of restrained streamlining who had been in charge of sheet metal and design techniques for Ferdinand Porsche since the VW Beetle. This new style of closed coupe designed by Komenda soon became the embodiment of the sports car, due in part to its “fastback”.

Erwin Komenda and Ferdinand “Butzi” Porsche, the founder’s grandson, continued this tradition with the 911.

The 911 became instantly recognizable: it had an attractive sloping bonnet reminiscent of the 356, what later became characterized as “frog eye” headlights, curves running from the top edge of the windscreen to the rear bumper, and a straight waistline. From a functional and technical point of view it shared more in common with a BMW 1500, but it retained the distinctive stylistic features of the original Porsche. The new 911 became the keystone of Porsche’s identity, even though the design was not always fully appreciated. During the 1970’s and 1980’s, many Porsche designers attempted to distance Porsche from its legendary design and nearly brought the company to the edge of disaster. The more modern 924 model, “a people’s Porsche”, developed with Volkswagen, as well as the 928 fell short fulfilling expectations, and failed to allow the company to branch out in new directions and styles.

However, in the 1990’s the company seemed to realize that what some perceived as a stylistic straitjacket was in fact a market advantage. During this period Porsche embraced the timeless nature of classic styling to become highly profitable. Nearly forty people now worked in the design department solely dedicated to further improvement of the long running 911. Such developments included the 911 GTI, put forward by the in-house designer Anthony R. Hatter as a powerful combination of sports and racing car. In 1999, Porsche’s chief designer proudly unveiled the new Boxster, enabling Porsche to establish a second independent range of successful models.
