The 3.0-litre, 6-cylinder petrol and diesel engines found in the BMW 640i and 640d Gran Coupe may not be considered the pinnacle of performance when slotted under the new BMW’s 1 900 kg body, but that hasn’t stopped renowned tuner AC Schnitzer from trying to improve the package.
In standard form the 640i produces 235 kW and 450 Nm, while the 640d produces 230 kW and 630 Nm of torque. The most notable difference between the two engines is the improved torque and economy of the 640d, as it consumes just 5.8 L/100km versus the 9.1 L/100km of its petrol sibling.
In the world of AC Schnitzer, after a bit of engine remapping and the fitment of a sports exhaust, the 640i and 640d will now both produce 265 kW, but interestingly there is no mention of torque increases. The AC Schnitzer goodie bag also includes a performance braking system with 8-piston callipers and a sports suspension with a lowering spring kit.
The exterior styling kit on offer comprises of: a front spoiler; chromed front grilles; a rear bumper apron; chromed ‘sports’ exhaust tips; and wheels as big as 21-inch, available in a few different designs. If you go for the full size 21-inch alloys, they wear a pair of 255/30-profile tyres on the front and 295/25-profile tyres on the rear.
On the inside an AC Schnitzer steering wheel replaces the standard item and aluminium is generously drizzled across the dash, peddles and iDrive controller. The AC Schnitzer Gran Coupe sounds and looks fantastic, but the tuner hasn’t released any fuel economy figures as yet.
Yes, we realise that last point is probably quite irrelevant, which is why we’re admittedly excited about the arrival of the ‘full fat’, 331 kW, V8-powered BMW 650i Gran Coupe that should be with us before the year is out. A bonkers 414 kW M6 version hasn’t been denied by BMW either – bring it on.
