Weber Sportcars Faster One: world’s fastest street-legal sports car

Article by Christian Andrei, on August 29, 2010

Swiss precision is no longer restricted to the sphere of producing the world's most celebrated watches. It's time for the WEBER SPORTCARS faster one! Using an exclusive mixture of ultra-modern engineering and inflexible ground-breaking styling designed for optimum aerodynamic efficiency, WEBER SPORTCARS from Tobel in the Swiss canton Thurgau designs and creates the fastest street-legal sports car in the world. The two-seater car weighs only a mere 1,100 kilograms and is propelled by a powerful V8 motor with double superchargers that generate 900 hp / 662.4 kW.

Courtesy of its exceptional power-to-weight ratio of 1.22 kilogram per hp, sharp all-wheel drive and stylish and sleek features the mid-engine racer accelerates from 0-100 km/h (62 mph) in 2.5 seconds, 0-200 km/h (124 mph) in 6.6 seconds, from 0 to 300 km/h (186 mph) in just 16.2 seconds and reaches a maximum speed in excess of 400 km/h (248.5 mph). Advantageous aerodynamic features are totally basic in order to achieve a ceiling speed in excess of 400 km/h. The body of the car by WEBER SPORTCARS faster one is measured at 204 centimeters wide and 115 centimeters high. It is finished totally from very light yet absolutely sturdy carbon fiber. High-tech aerodynamics computer program and wind-tunnel testing were utilized to trim the carbon-fiber shell for optimum directional stability at top speeds.

The aerodynamic downforce it generates is exceeded only by purebred racecars that do not have to conform with any legal requirements, such as ground clearance. The front of the car with its two quality WEBER SPORTCARS grilles appears almost vertical in contrast to that of rival sports vehicles, and is the intelligent result of the research conducted on aerodynamics.

This specific design produces an air wedge in front of the car with highly favorable effects on the airflow over the vehicle. The design of the upward-sloped hood, which extends all the way to the flush-mounted windshield, creates an aerodynamic downforce on the front axle to a pronounced advantage in directional stability. The headlamps with incorporated LED turn signals and the LED taillights were both created in-house by WEBER SPORTCARS. The fantastic sports car is 450 centimeters long, and highlights doors without handles for aerodynamic reasons. Instead these doors are opened and closed via a push of a button.

The two sleek side view mirrors offers excellent view of the rear. Incorporated into the roof is an air intake box that provides the engine precious air. Highly efficient air intakes incorporated into the rear of the car supply intercoolers and oil cooler in the engine bay with fresh air. The aerodynamic underfloor of the WEBER SPORTCARS faster one flares into a wide upturned Venturi tunnel in the rear.

This sleek trick adds to the creation of tough aerodynamic downforces as does the electronically adjusted rear wing. This advanced airfoil not only generates downforce but also doubles as an air brake. Contingent on present speed and driver-applied braking force the wing moves into a full vertical position in 50 milliseconds. That action generates up to 4,000 newtons of extra braking force. The WEBER SPORTCARS faster one supercar is propelled by a powerful V8 engine with a displacement of 7,011 ccm, dry-sump oil system and double superchargers. The motor is patterned on the LS7 engine, but of the original engine only the cylinder block and the fundamental design, that is, using one central camshaft and rockers for valve deployment, remain.

The lightweight aluminum block was improved with high-performance components such as a precision-balanced crankshaft, precision-balanced piston rods and forged pistons, a camshaft fitted with sharper timing, and two cylinder heads with bigger valves and intake and outlet ports tuned for maximum mixture flow. The engine peripherals were also changed extensively.

They currently consist of a customized high-performance fuel injection system and also a customized supercharging system with one mechanical belt-driven supercharger per bank of cylinders. Optimum boost pressure is restricted to 1.0 bars. The stainless-steel exhaust system highlights metal catalysts with low back pressure as well as a muffler bypass valve for a remarkable sound experience. The engine management system is rooted from the world of car racing and coordinates the perfect interface of all parts and parameters. Simultaneously buttons on the steering wheel provide the driver a choice selection of different mappings to adjust power output and throttle response to any particular driving situation.

The engine electronics also are responsible for passing the rigid EURO IV exhaust emission limits. The WEBER SPORTCARS faster one twin-supercharger engine generates 900 hp / 662.4 kW at 7,000 rpm and provides a top torque of 1,050 Nm at 3,900 rpm. The transmission was a proprietary enhancement by WEBER SPORTCARS which also builds it in-house. The semi-automatic sequential six-speed gearbox is operated through shift paddles on the steering wheel, the method popular in today's super sports cars.

Noteworthy was a tremendously brief shift time of just 50 milliseconds between gears, as well as highest durability under the massive strain of 1,050 Nm of gut-wrenching torque. The intelligent all-wheel drive system with active power distribution to all four wheels is also a proprietary enhancement from WEBER SPORTCARS. Electronically controlled differentials guarantee optimized traction under all kinds of road conditions and therefore always the best acceleration possible. More than 1/3 of the engine‚ power is channeled to the front wheels. The wheel trunks and suspension arms are created from a exceptional titanium alloy, the production process of which is quite expensive that not even F1 cars are so equipped!

The mixture of light-weight design, extremely powerful engine, sophisticated four-wheel drive, a dynamic traction control system patterned from Formula One racing and innovative aerodynamics gives the WEBER SPORTCARS faster one acceleration times formerly only attained by purebred racecars. The two-seater accelerates from 0 to 100 km/h in just 2.5 seconds and reaches 200 km/h after hitting 6.6 seconds.

Courtesy of its power-to-weight ratio and remarkably low drag it passes the 300 km/h-mark (186 mph) after just 16.2 seconds. Peak speed reaches more than 400 km/h (248.h mph). To achieve the anticipated performance WEBER SPORTCARS has developed an optimal interdependence of light-weight design, power and aerodynamics. The whole frame of the WEBER SPORTCARS supercar weighs only 65 kilograms and like almost all parts and tools it is produced in-house at WEBER SPORTCARS. It is made from high-class aluminum usually reserved for aerospace purposes. Retail prices begins at 1,620,000 Swiss Francs (export tag minus VAT) or $1,373,000 (€1,081,000).
