Road Performance

speed limit 300 km/h (off-road tire compromise, see above), speed at ~1000 engine rpm in the last gear 100 km/h
(at ~750 wheel rpm), acceleration 0-100 km/h ~3 sec., wheelie bars
Since 1973, the objective of our car-development has been to achieve by high-power turbodiesel engines
high torque with flat curves :  already basic 1000 Nm / 400 HP offer supercar-level also for lazy shifting,
just starting from idle, even in the last gear, drops consumption down and realizes a long-term-sense.  
The joy of driving shouldn’t be achieved by high speed but by agility and security.

Exclusive Construction of Chassis, Body and Suspension

weight reduction by monocoque and trapezoid tubular construction (only possible by central position of the driver)
despite overdimensioning (‘as a tank’), also for hard off-road-use, mostly stainless
robust long-term investment product, maintenance- and repairfriendly, under rigorous control hand-made
during about 8000 hours of top-level craftsmanship (‘as in old times’)
separate highbeam in the roof, opt.* LED or xenon for <=1 km; lowbeam, opt.* xenon or LED, LED daylight and foglight in the fender
complete dashboard, opt.* >=25 instruments also via display, ‘programming center’
opt.* :  A/C ‘to keep cool’, fridge, electrical hybrid drive EMA for front axle, ABS, ESP, GPS, etc.               
mid-engine touring and off-road supercar with air suspension ‘for Spartans’ (but comfortable for the spine,
adjustable in height to all terrain characteristics), spacious for 3 tall passengers and more than 500 l of luggage,
‘à la Paris-Dakar’, but also reliable and economical for everyday use
relaxing by the best relationship between torque and weight (RTW until ~1,4) :
Let Bugatti & Co. overtake your Sparta, of course !                                                     (basic price € 170.000.-- + VAT)

                                                               (titanium-version, among others with large axial fan rims, see above,  EUR 250.000.-- + VAT)
