What is it?
The new, 526bhp Shelby GT350R Mustang - and Ford isn't shy about what it has been benchmarked against during development. The Porsche 911 GT3 may undercut the big American coupé by a substantial 251kg, but the company with the blue oval badge claims the GT350R is faster than the rear-engined German around a circuit.
Clearly Ford isn’t messing around with its track-focused Mustang. And with the iconic American coupé finally on offer in the UK with right-hand drive, us Brits should be paying closer attention to its efforts than normal.
Part of the GT350R’s impressive pace is no doubt down to lightweight carbonfibre wheels and steamroller-wide Michelin Pilot Sport Cup 2 tyres. The 394mm Brembo brakes and magnetorheological adaptive dampers surely help, too.
But the real story here is the engine. Germany may be the focus for lap times but the influence under the bonnet is Italian. The new 5.2-litre V8 carries a sky-high 8250rpm redline courtesy of Ferrari’s favourite trick: a flat-plane crankshaft. In addition to changing the aural characteristics, a power bump comes along due to superior breathing.
Ford fiddled with the typical flat-plane crankpin set-up and fitted unequal-length 4-3-1 exhaust manifolds versus the usual equal-length 4-1 configuration. These changes help the Shelby sound more like a Ford V8 after too many shots of espresso, instead of a high-pitched southern European.
