The Noble M12 GTO-3R: A Closer Look At This Sports Car Including Performance, Technical Data, Features, Rivals Comparison, History, Used Pricing
from classic to modern
The Noble M12 GTO sports car was launched in 2000. Following its success, the company introduced the M12 GTO-3 in 2003, which included:
An extensively tuned 3-liter Ford Duratec V6 engine, equipped with twin Garrett T25 turbochargers, running at 0.7 bar of boost, and an intercooler.
Composite fiberglass body on a tubular steel space frame chassis
A substantial carbon fiber rear wing and front splitter that between them produced a marked increase in downforce.
Then in 2005, Noble released a variant aimed specifically at the track.
This was the Noble M12 GTO-3R two-door, two-seater, rear-wheel drive, which took over where the GTO-3 left off.
An important feature, only on the GTO-3R, was called the Auto Pair Bias Differential, produced by Quaife Engineering.
It was a form of limited slip differential that used helical gears, rather than clutch mechanisms, which were activated by mechanical or computer means.
The advantage of this system was that the power was concentrated on the particular wheel that required additional torque, such as when exiting a fast turn.
The particularly spacious interior of the cabin had leather trim, there was additional sound damping to reduce noise from both the engine and the track, it included an engine start button, both the seats and the steering column were adjustable and there was a full roll cage
As for the distinction between the two variants, the GTO-3R was equipped with covered dual headlights and a specially designed alloy steering wheel incorporating ten spokes.
It used AP Racing’s 13-inch vented and perforated discs throughout, and had a curb weight of just 1080kg, just 100kg more than the GTO variant.
Priced at $ 50,000, only 165 of the GTO-3Rs were built, with a substantially lower figure than the GTO and GTO-3 variants.
Powered by the same all-alloy DOHC 24-valve mid-engine as in the GTO-3, the five-speed manual gearbox was replaced by a six-speed manual Getrag unit in which the gear ratios were revised with the result that, when traveling at the legal speed limit, the engine was turning at just 2700 rpm.
The M12 GTO-3R’s engine developed 360 bhp at 6200 rpm, well below the 7200 redline, and 358 ft / lbs of torque at 3500 rpm, with most of the power available around 3000 rpm.
With a compression ratio of 8.5: 1, the car reached a top speed of 170 mph, with a 0-60 mph time of 3.5 seconds. Technical data:
Typical competition for the Noble M12 GTO-3R included the following sports cars: Porsche 993 GT2 Club Sport, Corvette ZO6, and Ford GT. Noble performance:

On the second-hand market, the typical asking price for an M12 GTO-3R sports car, in good condition, was between $ 51,000 and $ 58,000.
