AUTO WORLD BIKERS

The Chevrolet Corvette Grand Sport combines the Corvette's LS3-based powertrain with unique, wide-body styling and a racing-bred suspension for a distinctive model that delivers a great balance of road and race track performance. It is offered 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 elevates the power ratings to 436 horses (325 kW) and 428 lb.-ft. (580 Nm).

The Chevrolet Corvette 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 vs. standard LS3-powered models.

Chevrolet 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.

The complete list of content and special features for the Chevrolet Corvette Grand Sport includes:
Wider front and rear fenders - including specific front fenders with integrated Grand Sport badges
Z06-style front splitter and tall rear spoiler
Functional brake ducts and extra cooling
Unique 18-inch front and 19-inch rear wheels; painted finish standard and chrome finish optional
Large 275/35ZR18 tires in front and 325/30ZR19 tires in the rear
Z06-size brakes, including 14-inch (355 mm) front rotors with six-piston calipers and 13.4-inch (340 mm) rear rotors with four-piston calipers
Specific manual transmission gear ratios
Specific rear axle ratio on automatic-equipped models
With its special equipment, the Chevrolet Corvette Grand Sport offers a unique blend of performance and amenities. Its suspension package approaches that of the Chevrolet Corvette 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.
All of Corvette's exterior colors are offered on the Chevrolet Corvette Grand Sport, and an available Heritage package adds iconic front fender hash marks offered in four colors, as well as two-tone seats with Grand Sport embroidery. The Chevrolet Corvette Grand Sport can be ordered with 1LT, 2LT, 3LT and 4LT trim packages, too.

Grand Sport history

Envisioned by legendary Corvette engineer Zora Arkus-Duntov as a factory-built, lightweight and race-ready production model that would trump domestic and foreign road-racing competitors, the original Chevrolet Corvette Grand Sport was a promising idea that led to the production of five special prototypes in 1963. The project was later shelved, following GM's agreement to stay out of manufacturer-backed motorsports.

The five prototypes were based on the styling of the 1963 Corvette and were hand-assembled under Duntov's watchful eye. But while they looked like production models, the prototypes were purpose-built race cars that shared little with their assembly-line cousins. Duntov also oversaw the Chevrolet Corvette Grand Sport engine program that featured a special, 377-cubic-inch small-block V-8 with side-draft carburetors.

Although never officially sanctioned by General Motors, the five Grand Sport prototypes saw extensive racing experience throughout the 1960s in the hands of "private" racers who had strong contacts within Duntov's engineering circle. All five original cars are accounted for today and are among the most valuable in the collector market.

Chevrolet offered a limited-edition  production model in 1996, commemorating the original racing cars and marking the end of the C4 era in Corvette production. All of the 1,000 examples were painted Admiral Blue and featured a white center stripe and red "hash mark" graphics on the left front fender, a graphic scheme that mimicked the look of some of the original race cars.

The Ferrari Enzo with its 660 horsepower is arguably one of the most exclusive cars in the world, both in terms of its driving dynamics and purchase price. Those looking for something considerably faster and more exclusive choose the edo Ferrari Enzo XX Evolution.

A bump in displacement from 6.0 to 6.3 liters, new camshafts, new titanium valve spring retainers and connecting rods, modified cylinder heads, new high performance exhaust headers, high flow catalytic converters, mufflers and air filters: that's the scope of edo competition's engine modifications. The standard hydraulic tappets are replaced with newly developed solid tappets, enabling the 12 cylinder engine to rev to an incredible 9,600 rpm. This is unmatched by any other 12 cylinder engine at this time! Additionally the intake system of the V12 was modified, a new high performance clutch - available with „strada" or „pista" friction pads - and a more powerful oil pump were installed. The power output is increased by 180 to 840 horsepower. Without mufflers more than 860 horsepower is possible. The maximum torque of 780 Nm (575 ft-lb) is available at 5,800 rpm.

While the power output is increased, the Ferrari Enzo's weight is decreased by a respectable 100 kilograms (220 lb). The result in numerical terms is that the edo Ferrari Enzo XX Evolution accelerates from zero to 100 km/h (62 mph) in 3.2 seconds, 200 km/h (124 mph) in 9.0 seconds and 300 km/h in just 19 seconds. The top speed exceeds 390 km/h (242 mph).The acoustical side of things is obviously not being neglected. A stainless steel muffler featuring remote-controlled butterfly valves is available on request. This setup lets the driver switch the high performance exhaust between two different sound levels.

Astonishing transmission shift times: While the production Enzo takes 110 milliseconds, the edo Ferrari Enzo XX Evolution shift times were reduced to an incredible 60 milliseconds! For comparison, an F1 car shifts in 40 milliseconds.

The edo/KW race suspension from the FIA GT series was retuned for the Enzo XX Evolution, promising ultimate driving dynamics. The nose lift functionality is retained. The low-friction 3-way adjustable shock absorbers can be adjusted to the individual tastes of the driver and provide excellent steering precision and feedback. The edo-installed tire pressure monitoring system displays the pressures for each of the four wheels. Providing ample grip for the edo Ferrari Enzo XX Evolution are 19 inch front wheels and 20 inch rear wheels with 335 mm wide tires.

The drive shafts were replaced due to the higher propulsive forces acting on them. The new units are 4 kg (8.8 lb) lighter and considerably more robust in order to cope with the enormous power increase.

The aerodynamics package is absolutely unique. It includes a complete exhaust system with tips machined from billet aluminum, now relocated to the top of the body. The tips are plasma-coated using a special process. The newly developed rear skirt featuring winglets and a rear wing profile, adjustable in 3 steps, improves the ground effect and can be tuned to the tastes of the driver. The new retractable rear wing is upgraded with a taller flap resulting in increased downforce and stability, especially at high speeds. New LED tail lights round off the rear view of the car.

A test day with an instructor, mechanics, data logging, transport and hospitality is included in the conversion package.

Unveiled at the 2002 North American International Auto Show, the Ford GT40 concept became an instant sensation. And just 45 days after the vehicle was unveiled, Ford stunned the world again, officially announcing that a production version was in the works. Ford's GT40 concept car was created to celebrate that great era in history and look forward to the great years to come.Although the new production car and the original race car both share the mystique of the Ford GT name, they do not share a single dimension. The new car is more than 18 inches longer and stands nearly 4 inches taller. Its new lines draw upon and refine the best features of Ford GT history and express the car's identity through modern proportion and surface development.

The Ford GT production car, like the concept, casts the familiar, sleek look of its namesake; yet every dimension, every curve and every line on the car is a unique reinterpretation of the original. The car features a long front overhang reminiscent of 1960s-era race cars. But its sweeping cowl, subtle accent lines and high-intensity-discharge (HID) headlamps strike a distinctly contemporary pose.

Race History

The original Ford GT40 racers were engineering and design marvels demonstrating Ford's dedication and perseverance. In a few short years, under the direction of Henry Ford II, the company built a program from scratch that reached the pinnacle of international motorsports competition - and stayed there for four racing seasons.

Perhaps the world's most significant - and glamorous - motorsport contest, Le Mans in the early 1960s was showing signs of becoming a Ferrari showcase, because the Italians had become the leaders in a number of endurance classes and events. But the Ford GT race car changed Le Mans forever, and today it signifies a new era for Ford Motor Company.
