The Noble M400 is a sports car from the British car maker Noble. Manufacturing was outsourced to Hi-Tech Automotive, based in Port Elizabeth, South Africa. The M400 was noted by the automotive press for excellent handling and power. The Noble M400 features a mid-mounted transverse engine design. The power plant began life as a 2, 968 cc DOHC Ford Duratec V6 with four valves per cylinder, as used in the Ford Mondeo ST220. With this engine as a base, Noble fits high-lift camshafts, revised fuel injection, and two turbochargers. For durability, Noble also added forged pistons, an oil cooler, a larger baffled oil sump, and extra cooling ducts. Its engine has a maximum power of 425 bhp (317 kW) at 6, 500 rpm, with a torque figure of 390 lb·ft (530 N·m) at 5, 000 rpm. This power and a light weight allow the M400 to achieve a power-to-weight ratio of just over 400 bhp/ton, the figure for which it was named, a 0–60 mph (97 km/h) of 3.2 seconds and a 1/4-mile time of 11.4 @ 119.8 mph (192.8 km/h).[7][3] Top speed is 187 mph (301 km/h). The UK automotive TV show Vroom Vroom suggested that the M400 gave Ferrari Enzo performance at a Porsche 911 price.
