Grand Sport coupe Chevrolet Corvette LS3 6.2L engine.
The Corvette Grand Sport is available in both coupe and convertible body styles, with either a six-speed manual or six-speed automatic transmission. The LS3 6.2L engine is rated at 430 horsepower (321 kW) and 424 lb.-ft. of torque (575 Nm) with the standard exhaust system. An optional two-mode exhaust system raises the power output to 436 horses (325 kW) and 428 lb.-ft. (580 Nm).
The 2010 Chevrolet Corvette Grand Sport which was introduced at the 12th annual C5/C6 Corvette Birthday Bash, held at the National Corvette Museum, in Bowling Green, Ky. combines the Corvette’s LS3-based powertrain with unique, wide-body styling and a racing-derived suspension.

The Grand Sport replaces the Corvette’s previous Z51 package and brings a greater degree of handling performance, with wider wheels and tires; revised shock, stabilizer bar and spring specifications; and specific gearing. The equipment enables cornering capability of 1.0 g, as well as a 0.2-second improvement in 0-60 acceleration over the standard .
With its special equipment, the Corvette Grand Sport offers a unique blend of performance and amenities. Its suspension package approaches that of the Z06, but includes a removable roof on coupes (Z06 has a fixed roof) and, of course, the availability of a convertible body style. Also, the paddle-shift six-speed automatic transmission is offered, while a manual transmission is the only choice with the Z06. Essentially the Grand Sport sits somewhere between the standard C6 Corvette and the Z06 Corvette for performance and comfort.
Corvette Grand Sport coupe models equipped with the manual transmission are uniquely outfitted for race track competition, too, with a dry-sump oiling system, differential cooler and a rear-mounted battery - this is the model you want to go for, otherwise you're wasting your money and may as well get the standard model.

The Aston Martin Rally GT, based on the Aston Martin V8 Vantage, was developed by Aston Martin Racing and automotive engineering specialists Prodrive (see Prodrive P2) for use in rally racing.

The Aston Martin Rally GT was extensively engineered by Prodrive, and like the DBRS9 based on the Aston Martin DB9, the Rally GT is based on a standard road car's chassis. However the Rally GT has been fitted with a Prodrive rollcage, a tuned and more responsive version of the standard car's 4.3 litre V8, and new competition Eibach springs and adjustable EXE-TC dampers. The 6-speed transmission is the same unit found in the road car, but it can be upgraded to a close ratio dog engagement gearbox specifically developed for the Aston Martin Rally GT.

The Austin Healey 3000 was the replacement car for the Austin Healey 100/6. The Austin Healey 3000 was a superior car to its predecessor, equipped with many improved features and updated parts. During its production lifetime the Austin Healey 3000 went through three different versions, the MK I, MK II and MK III.
The Austin Healey 3000 MK I (1959 - 1961) was fitted with a 3.0 litre inline six cylinder engine developing 124 horsepower. The engine was equipped with twin SU carburetors. And the car featured disc brakes at the front.
The Austin Healey 3000 MK II (1961 - 1963) introduced several improvements and design changes. The engine was enhanced by the fitment of triple SU carburettors which bumped the power up to 132 horsepower. In 1962 the BT7 2+2 version was introduced. This seating layout became the only option from 1962 onwards. The Austin Healey 3000 MK IIa introduced wind-up windows, a curved windscreen, and a convertible hood.

The Austin Healey 3000 MK III (1963 - 1967) was the final version of the 3000 model. The performance was improved due to engine modifications. Peak power was raised to 148 horsepower, giving the 3000 MK III a top speed of 120 mph. The brakes were also enhanced with the fitment of a servo.
In 1967, due to new safety regulations in the cars biggest market - America, the Austin Healey 3000 was discontinued. It's replacement, the MGC, was nowhere near as popular as the Austin Healey 3000.
During its lifetime the Austin Healey 3000 proved to be a capable racing car. And it competed successfully in rally and road races around the world.
