Most powerful variant will be the V6-powered 'AMG Sport'.
According Auto Express UK, a full fledged V8-powered AMG version of the GLC (or Mercedes GLC 63 AMG) is unlikely to happen.
Although the new GLC is based on an extended version of the C-Class's MRA platform, which could support the AMG GT's 4.0-Liter Bi-Turbo V8 engine (as seen in the Mercedes C63 AMG), Mercedes have decided to not offer a top-of-the-line V8-powered AMG version, reportedly.
However, AMG will play a role in the development, as the SUV will be available in a less-powerful 'GLC AMG Sport' variant. Likely to be called the Mercedes GLC 450 AMG, it will pack a 362-bhp 3.5-liter twin turbo V6 engine from the C 450 AMG, which will serve as the top-spec variant for the GLC range.
Like the C450 AMG, Merc's Skunkworks division will tune up the suspension for better road handling as well as adjust the torque bias of the 4MATIC AWD system for more power at the rear, resulting in a relatively spirited driving performance.
At launch, the Mercedes GLC will be available with 2.0L petrol and diesel engines, that will come paired to a new 9G-TRONIC automatic transmission as standard. The Audi Q5 rival will make its global debut on June 17, while an Indian launch is expected in the first half of 2016.
