In all likelihood, the CLA35 will be more or less the same, powertrain-wise, as the A35, given the shared number on the badge. If that pans out, that means the CLA35 will wield a 2.0-liter turbocharged I4 that makes 302 horsepower and 295 pound-feet of torque, a fair bump over the CLA250's 221-hp, 258-lb-ft engine, which is already about 30 hp above the A220's four-pot.

In terms of performance, the A35 is able to reach 60 miles per hour in just 4.7 seconds, so it stands to reason that the CLA35 will get there in about the same amount of time. Other additions to the A35 that we should expect to see on the CLA35 include a stiffer suspension, bigger brakes and a retuned variable steering system.
