The Noble M400 is a sports car from the British car maker Noble. Manufacturing was outsourced to Hi-Tech Automotive,[1][2] based in Port Elizabeth, South Africa. The M400 was noted by the automotive press for excellent handling and power.[3][4][5]

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.

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.[6] 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 14 mile (402 m) time of 11.4 at 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.

Rossion Q1[edit]

Noble no longer manufactures the M400. The exclusive dealer for Noble in the US, 1G Racing in Ohio, USA (also known as Rossion), has obtained the production rights to the M400 from Noble Automotive, and has released an updated version named Rossion Q1. 1G's version of the M400 includes a redesigned aerodynamic shell, a new interior and an upgraded engine management system, upgrading it to 450 bhp (336 kW).[8] 0-60 mph (97 km/h) has dropped from 3.3 seconds to 3.1.[9] Its top speed changed to 189 mph (304 km/h).
