MG Metro 6R4 - Twin Turbo

(aka 'Growly')


This is the fastest MG Metro 6R4 in the world.
It is a former 1980/90's FIA European Rallycross car that is now in Time Attack / Hillclimb / Sprint specification.

Used in period by Arne Rasmushaugen and Bengt Wiklund.

It was extensively rebuilt and upgraded in 2012 by and subsequently

claimed 2nd overall in the UK Time Attack championships driven by Mark Pollard.

It won the PRO class final at Brands Hatch in 2014 driven by Dr Ian Rowlance.

In 2015 it took a new saloon car record and class win at the Cholmondeley Pageant of Power.

Having driven all types of normally aspirated 6R4's, this car is on another level of performance.

Breathtaking accleration and terminal speeds are more on a par with single seaters than Group B.

It has many upgrades inlcuding all the usual modern electronics expected from our cars.

Electronic Boost control allows the power to be turned up from 600bhp to over 800bhp at the turn of a dial .
