From Noble press: Noble Automotive to developed the M400, a car that takes full advantage of the scope left in the M12's chassis and engine for drivers who seek even more focus in their performance and dynamics. With a power to weight ratio of 400bhp per tonne (hence the name), the M400 is not only substantially more powerful than the other cars in the M12 range, but it also showcases a variety of unique features not seen in other Nobles.
The M400 is not only one of the fastest production cars of its type, but its chassis - which in standard M12 form uniquely marries high-speed composure with low-speed ride compliance - has now been sharpened to give the driver even greater control of the car at speed.
At the heart of the M400 is the 3.0-litre, 24-valve V6 engine that can be found in the current M12 range. However, power is now increased by 21 per cent to 425bhp and torque by 11 per cent to 390lb ft.
Internally, the engine has been modified with higher-lift cams and forged, rather than cast pistons, for extra strength. The forged pistons have been included as a safety feature for the engine, rather than out of necessity: in fact, the development car that spawned the M400 has covered many thousands of reliable miles on cast pistons with an even higher output than the production M400. Add to this the usual tuning recipe that goes into each and every Noble engine, and owners can be assured of plenty of durable high-performance.
