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.[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 1⁄4 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.

About

The M400 is the track variant of the M12. Its power-to-weight ratio is over 400 bhp (300 kW) per ton, and is the figure from which its model name derives. It has 425 bhp (317 kW; 431 PS) and has been reported to do 0–60 mph (0–97 km/h) in as little as 2.97 seconds. Car and Driver (March 2007) achieved a 0–60 mph time of 3.3 seconds and a 0–100 mph time of 7.52 seconds. Although often listed as 0–60 mph in 3.5 seconds, the M400 generally comes in at 3.2 seconds according to various publications and generally listed amongst the fastest accelerating cars. Noble indicates only that the car is capable of achieving 0–60 mph in under 4 seconds. Its top speed is listed as 185 mph (300 km/h). A top speed of 202 mph (325 km/h) has been achieved by Noble's former press officer. Lateral Gs are reported in excess of 1.2. It has both a 3-point seatbelt and a 5-point harness.

The most notable differences from the M12 are the use of forged pistons, T28 turbos, a front anti-roll bar, stiffer springs, different shocks, Pirelli P Zero tyres, a smoother gear shifter, and a slightly narrower central tunnel as the driver now sits a bit more central than previous models. Exterior differences remain subtle. The colour scheme tends to incorporate anthracite (Gris) wheels, rear wing supports and wing ends but some examples maintain silver wheels and supports. The front splitter is now removed (Although many owners opt to have this put on). The main change is the addition of side pods to enhance air into the system and to create a visual impact. Air conditioning was an £1,995 option and adds to the weight. The interior has an added oil gauge that resides next to the boost one. Additionally the Sparco Alcantara seats and finishings differ from the other Noble's (Alcantara is one third the weight of leather). The Noble M400 won the car of the year award in 2005 by one publication. The M400 is designed to be an outstanding track car that is also pleasant to drive on the road. With just 75 examples made this version is sought after and rare.

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. The Rossion Q1 uses a updated M400 platform, 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).
