The Weber Sportcars supercar is powered by a V8 engine with a displacement of 7,011 ccm, dry-sump oil system and dual superchargers. The engine is based on the LS7 engine but of the original engine only the cylinder block and the basic design using one central camshaft and rockers for valve activation remain.

The lightweight aluminum block was upgraded with high-performance parts such as a precision-balanced crankshaft, precision-balanced piston rods and forged pistons, a camshaft with sharper timing, and two cylinder heads with larger valves and intake and outlet ports tuned for optimal mixture flow.

The engine peripherals were also modified extensively. They now include a custom-developed high-performance fuel injection system and an also custom-developed supercharging system with one mechanical belt-driven supercharger per bank of cylinders. Maximum boost pressure is limited to 1.0 bars.

The stainless-steel exhaust system features metal catalysts with low back pressure as well as a muffler bypass valve for an impressive sound experience.

The engine management system stems from the world of car racing and orchestrates the perfect interaction of all components and parameters. At the same time buttons on the steering wheel give the driver the option to select different mappings to adjust power output and throttle response to the specific driving situation. The engine electronics also are responsible for meeting stringent EURO IV exhaust emission limits.

The twin-supercharger engine delivers 900 hp / 662.4 kW at 7,000 rpm and produces a peak torque of 1,050 Nm at 3,900 rpm.

The transmission was a proprietary development by Weber Sportcars which also builds it in-house. The semi-automatic sequential six-speed gearbox is operated via shift paddles on the steering wheel, the method of choice in today’s super sports cars. Of special importance was an extremely short shift time of just 50 milliseconds between gears, as well as maximum durability under the enormous strain of 1,050 Nm of gut-wrenching torque.

The intelligent all-wheel drive system with dynamic power distribution to all four wheels is also a proprietary development from Weber Sportcars. Electronically controlled differentials ensure maximum traction under all road conditions and thus always the best-possible acceleration. Up to 36 percent of the engine’s power is transferred to the front wheels.

The combination of light-weight design, enormously powerful engine, high-end four-wheel drive, an active traction control system derived from Formula One racing and innovative aerodynamics gives the Weber Sportcars supercar acceleration times previously only attained by purebred racecars. The two-seater sprints from rest to 100 km/h in just 2.5 seconds and reaches 200 km/h after just 6.6 seconds. Thanks to its favorable power-to-weight ratio and exceptionally low drag it passes the 300 km/h-mark after just 16.2 seconds. Top speed is more than 400 km/h .
