2020 Mercedes-Benz SLC-Class Performance

Besides the fire-breathing AMG model which we review separately, there is only one engine doing duty in the SLC: a 2.0-liter turbocharged inline-four with 241 horsepower and 273 lb-ft of torque, transferred to the rear wheels via a nine-speed automatic transmission. The combination is enough to complete the zero-to-sixty run in 5.8 seconds - it's rapid but not as quick as the base BMW Z4's time of 5.2 seconds. The top speed is electronically limited to the usual 155 mph. The SLC's performance is all very composed and easily attainable, but it's also not what you'd call dramatic or exciting. If you want something with more of a kick, go for the AMG model, but even then, you'll miss the old V8 howl.

Merc's baby roadster was once offered with a bellowing naturally aspirated V6 in base form, but the SLC300 has used a more efficient 2.0-liter four-cylinder with turbocharging for a few years now. The outputs of 241 hp and 273 lb-ft are plenty for most needs. The engine is paired with a nine-speed automatic transmission with paddle shifters and a Dynamic Select system that allows drivers to alter throttle response and the gearbox's shift points from the efficient ECO mode to the more intense Sport +.

It's not bad, it's just not as good as the best. Passing power is otherwise ample and the transmission executes smooth up- or downshifts, although it can be slow to respond in manual mode. Driven hard, the SLC300 feels out of its element, preferring a more mellow approach that will appeal to many but frustrate those looking for a more engaging experience.

The SLC's EPA-rated economy estimates match those of the BMW Z4 while bettering the Porsche Boxster's figures. It achieves 23/32/27 mpg on the city/highway/combined cycles, enough to travel about 429 miles when the 15.9-gallon gas tank is filled up. This is better than the latest available figures for the Porsche Boxster (22/29/25 mpg in its most fuel-efficient guise) and nearly identical to the BMW Z4 sDrive30i's 24/32/27 mpg, but it's worth noting that the SLC requires premium gasoline.
