The Sirius is built around a carbon-fibre tub with tubular steel front and rear subframes, off which the powertrain and suspension are hung. The body panels are carbon-fibre, and both front and rear clamshells are hinged to open forwards, while the doors open upwards Lamborghini fashion.

With his racing background, Kurt believes in low weight and big power. So the 1,390kg Sirius uses a twin-turbo version of the robust 48-valve 5,987cc Mercedes V12 -- as used in the Pagani Zonda.
With twin KKK K27 turbos, the Porsche tuner's favourite, set to boost at 0.85 bar, it makes a thundering 850bhp at 6,000rpm with a tarmac rippling 1,000Nm (738 lb ft) of torque at 3,800rpm. This is transmitted to the rear wheels through the same six-speed manual CIMA gearbox used by Ascari, Koenigsegg and Pagani, sitting behind the engine racecar style, with its own oil cooler. The transmission package includes a limited slip differential, while electronic traction control provides a welcome safety net.
Suspension is by race-style unequal length double wishbones with inboard coil-overs, Koni dampers and anti-roll bars. The huge race grade cross-drilled ventilated discs are clamped by big four-pot calipers with servo-assistance and ABS. 255/35ZR19 and 345/30ZR19 Michelin Pilot Sport tyres on very light Japanese-made 9.5J and 12.5J x 19-inch WORK forged alloy wheels provide amazing levels of grip.
Lotec claims 0-62mph in 3.8 sec, 0-124mph in 7.8 sec and a 244mph top speed with the tallest final drive. However, the company has dyno-tested engines in two higher states of tune. “We achieved 1,000bhp with 1,200Nm on 1.0 bar boost, and 1,200bhp with 1,340Nm on 1.2 bar,” Kurt said.
With limited resources at hand, production would mean a maximum of four cars a year, so the Lotec Sirius is not exactly going to paint its rivals into a corner. However, its stunning futuristic looks and interstellar performance are a loud wakeup call to the big boys.
