The unveiling later tonight of the third supercar from AMG, the GT, presents the company with its clearest sight yet of an open goal. 

The original AMG machine, the troubled SLR project built by AMG’s uncomfortable then-bedfellow McLaren, was never seen as a front runner. The second car, the SLS, was much loved by some owners but its size and price were barriers for others. 

Now comes the GT, which keeps the SLS’s good bits but drops the price by about 30 per cent. It's managed to do that by a) not having the hard-to-engineer gullwing doors, and thanks to b) AMG, being a restless technology company, finding better, quicker, cheaper ways of producing the exotic structures needed.

Better still – some will think – there’s new 4.0-litre twin turbo V8 that moves the new car well up the efficiency pole from the SLS’s thunderous 6.3-litre bent-eight, though many will regret the passing of such an iconic lump.
