He left the company in February 2008 and shortly after announced his new venture, Fenix Automotive in 2009.
The body and chassis of the Noble is built by Hi-Tech Automotive in Port Elizabeth, South Africa alongside Superformance cars.
In 2009 Noble released the M600 with 650 bhp (485 kW) available from its 4.4-litre V8 Volvo derived twin turbocharged engine with a Graziano 6 speed manual gearbox.
Due to high demand of these cars, 1G released its own copy, named Rossion Q1.
Its power-to-weight ratio is over 400 bhp (300 kW) per ton, and is the figure from which its model name derives.
The most notable differences from the M12 are the use of forged pistons, Universal Turbos Ltd Supplied Garrett 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.
The main change is the addition of side pods to enhance air into the system and to create a visual impact.
The Noble M15 was intended to appeal to a far broader market and compete directly with the Porsche 911 Turbo and Ferrari F430.

According to founder Lee Noble, "I wanted to produce a supercar people could use every day.
It was time for Noble to take a big step up in terms of refinement, practicality and style.
According to Richard this has to do with the new, stronger gearbox which enables Noble to allow more boost and let the same engine produce more power.
It has a Volvo twin-turbocharged V8 engine (producing 650 bhp, 485 kW, 659 PS), a carbon fibre body shell, and a 6-speed Graziano gear box.
It does have TCS as standard, although this can be totally disabled via a fighter jet style missile switch.
Noble publicly tested an M600 prototype 2 in the US, comparing its performance with a Porsche Carrera GT and Ferrari Enzo.
According to UK enthusiast website ATFULLCHAT Noble Automotive have not ignored the possibility of building an M600 roadster.
On 21 June 2012 the website published a rendering of an M600 drophead that was commissioned internally by Noble Automotive, although company MD Peter Boutwood is quoted as stating there are no plans at present to produce such a machine.
Initial projected production would be limited to fifty cars and at least thirty were produced.
