You might think that 6 liters was enough to make the Corvette two-seater fast enough, but not for the competition department lurking inside GM. They wanted to be able to compete head-to-head with the European supercars in the international endurance races for sports cars.

To do this, they list from Ford's book. In the 1960s, when Ford thought it could not compete with the smaller Ferraris at Le Mans with a 4.2 (ex-Indy) or 4.7 liter engines, they brought their 7-liter mill. And it is so much bigger than the competition which they won. So, the guys behind the Corvette decided to produce a 7-liter version of America's favorite and most famous sports cars.

Incidentally, the 7 liter Corvette more than competes with the Dodge Viper SRT-10, which could give the standard Corvette a little run for their money. Of course, it is not just any old engine. This is a very special version of its Gen IV 7.0-liter V-8.

This is a 2006 Corvette is a challenge for the muscle car with no less than 500 hp on tap at 6200 rpm. Maximum torque of this engine is a huge £ 475 ft at 4800 rpm. This is bound to be a stunner with a top speed of 185 km / h, and about 00-60 under 4.0 seconds. GM expects to be a quarter mile under 12 seconds.

To the durability, the engine has been improved in numerous ways. First, connecting rods and intake valves are now made ​​of titanium - I weigh about half as much as steel ones and are used in a very large number of high-performance engines. Due to the lightweight titanium parts to put less load on other critical engine parts - crankshaft, bearings and in this case the valve as well. titanium valves and allow the engine to rev faster safely.

In fact, titanium is used to space just because the material was so expensive, but it's now the bone gused more exotic cars and heads of golf clubs, helping the less the pros do not feel so outclassed by Tiger Woods as they could with ordinary drivers.

You will see Corvette 7 liter is intended to track the fact that the engine has a dry sump lube system. dry bed of the system prevents the oil in a pan of oil discharge away from the pick-up at high speed corners - the type you can only do so on the trail -. and thereby damage the main bearings

Instead of staying in the oil pan, oil is pumped out to the mailbox, and then pressure fed from there directly to the engine bearings and other critical areas. Definitely a system for the top cars.

base cars are also improved with a new aluminum perimeter frame that reduces weight. Further weight reduction comes with a new magnesium engine sub-frame. To ensure the car is stiff enough, it will only be available as a hardtop. front wings and wheelarches are now carbon fiber composite panels, which can also reduce weight.

But there is more ...

to get all that power onto the road and to get it to stop, bigger wheels, tires and brakes are fitted. Front brake discs are now 13.9 inches in diameter, and 19 x 12 inches wide rims are used in the back, the front wheels are 18 x 9.5 cm. Such a massive rear tires for a car with a 50:50 weight distribution indicates that the car will have a tendency to oversteer - smoking causes could be the order of the day

All-in-all, this is truly a special car, developed to compete with the best.
