[7] The MG6 sold below expectations in the United Kingdom, eventually being dropped from the range there in 2016, whilst continuing in other markets.

The MG6 commenced production in China in 2010, and for a brief period in partially knock down form at Longbridge, United Kingdom, from 13 April 2011.

In the United Kingdom, the car was initially launched as the MG6, but on release to the public in May 2011 as the fastback model, was announced as the MG6 GT.

[13] The 1.8 L turbo can accelerate to 60 mph in 8.4 seconds, has an official combined fuel consumption of 35.6 mpg and a CO2 figure of 184 g/km.

[14] Minor improvements to the MG6 in April 2012 resulted in fuel economy figure of 37.7 mpg (official combined) and reducing CO2 down to 174 g/km.

[16] The diesel engine is mated to a six-speed manual gearbox, and the steering has changed to an electro hydraulic-powered system.

[19] The MG6 was facelifted for April 2015, receiving a range of exterior and interior changes including a 75 kg (165 lb) reduction in weight.

[20] In the United Kingdom, the main mechanical changes comprised an improvement in efficiency for the diesel model, and the withdrawal of the petrol version.

The facelifted model can be identified by its new lights and bumpers, front and rear, and a substantially updated interior, including a new console and electronic parking brake.

In the Auto Express Driver Power Survey in 2014, it won the Best Handling Award, and came sixth overall in the 'Best Car to Own' category.

[24][25] Some cited lack of advertising and low perceived quality as problematic, while the absence of a diesel and an estate option were also mooted.

[28] Initial production was projected in the range of 2,000 to 3,000 per annum, although these volumes were never achieved, and in 2016, MG Motor UK withdrew the MG6 from sale in the United Kingdom.

While marketed as a super wide-body sedan, the width is actually the same as the pre-facelift model with the redesigned front and rear end resulted in a 9 mm (0.4 in) length growth instead.

As for the powertrain, the MG6 X-Power has a straight-4 1.5-litre turbo-charged engine with an electric motor with combined outputs of 300 hp (220 kW; 300 PS) and 480 N⋅m (354 lb⋅ft; 48.9 kg⋅m) of torque, sending its power to the front wheels.

Exterior colour choices are Qi Ji Green, Flame Red, Carbon Gray, and Obsidian Black.

The standard interior is a two-toned textured interior consisting of a charcoal black base with green accent stitching and charcoal black sporty leather bucket seats with an X-Power logo stitched into the front lower seat area.

Design wise, the MG6 Pro features a redesigned front end with slimmer headlamps and a larger grille in the same style as the second generation MG 5 for a more aggressive look.

[47] Available exterior colours are known as Bubble Orange, Thunder Gray, Obsidian Black, Pearl White, and Flame Red.

The X-Line still runs on the same 1.5 litre turbocharged petrol engine and 7 speed dual clutch automatic gearbox as standard.

The team returned in 2013 with Sam Tordoff replacing Neate in the second MG, who performed well in his debut year having joined through the KX Academy scheme.

After just three years of competition, the MG6 GT sealed the title by 95 points at the season finale at Brands Hatch.

On 8 March 2016, Triple Eight Racing confirmed that Josh Cook and Ashley Sutton would drive for the team in the 2016 British Touring Car Championship.
