context_page_description: The Noble M400 is a rare 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.
context_section_description: The Noble M400 features a transversely-mounted rear mid-engine, rear-wheel-drive layout. The power plant began life as a 2,968 cc (3.0 L; 181.1 cu in) DOHC with 4 valves per cylinder Ford Duratec V6 engine, as used in the Ford Mondeo ST220. With this engine as a base, Noble fits high-lift camshafts, revised fuel injection, and Garrett AiResearch T28 twin-turbochargers. The M400 has no ABS, no stability control, no traction control, and no air bags. Driver safety comes from a factory racing harness and built-in roll cage.
  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 (431 PS; 317 kW) at 6,500 rpm, with a torque figure of 390 lb⋅ft (529 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 (406 PS; 298 kW)/ton, the figure for which it was named, a 0–60 mph (97 km/h) of 3.2 seconds and a ¹⁄₄ mile (402 m) time of 11.4 at 119.8 mph (192.8 km/h).  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.
