The C-Class is Mercedes-AMG's best-selling model series, and now the firm has unveiled what it says is the sportiest C-Class ever. The C 63 Coupé can accelerate from 0-100 km/h in four seconds. That makes it faster than its predecessor, which held the crown of fastest C-Class ever.
At what point does a hot hatch become a pint-sized sports car? The Mercedes A45 AMG was already blurring the line, but the engineers over at AMG's Affalterbach headquarters decided that the pint-sized turbo terrier needed more power. Thanks to an extra 15 kW (20 hp) from its 2.0-liter motor, the updated A45 AMG will now hit 100 km/h (62 mph) in just 4.2 seconds.
