We’ve not managed to cover the BMW Z4 so far so we might as well kick off with an impressive tuned version of the Bavarian company’s roadster.
There’s plenty with more performance and there’s plenty with more aggressive body kits but the AC Schnitzer ACS 99d is miles more impressive.
This is because it gets a new (and unexpected) engine and it also loses a whopping 507 pounds off what is already a decently lightweight vehicle.
The first part is taken care of as AC Schnitzer have dropped the engine originally fitted by the factory and opted for the one you get in the 320d EfficientDynamics Edition.
Well known as an incredibly efficient powerplant, AC Schnitzer have taken it one point further and while they were at it they made it a little more powerful as it now develops 190 horsepower.
Team that up with a new body kit that’s made completely out of carbon fiber, the reduction of unsprung weight and the fitting of 19″ lightweight alloy wheels with titanium bolts and you get a lot of benefits.
Lighter weight, better distribution of what’s left and even better fuel economy levels. It is also part of helping the handling.
That’s where the revised AC Schnitzer suspension, new brakes and Continental Sport Contact high performance tires help finish the thing off.
The end result is that the AC Schnitzer ACS 99d is a sports car which goes from 0 to 62 in 6.9 seconds yet only consumes 3.8 l of fuel per 100 km and emits less than 99 g of CO2 per km.
This is the sort of efficiency that is impressive even in horrid little eco-boxes let alone great handling and fun sport cars.
