2020 BMW M340i Drag Races Audi S4 and Mercedes-AMG C 43

Throttle House was eager to settle the score and lined up these three German machines for a drag race. More than a year ago, they did a comparison review of the same cars (in different colors), and said the C 43 was more exciting while the M340i probably had the nicest interior.

Nothing has changed since then in the powertrain department. The king of this power hill is the C 43, motivated by a twin-turbo V6 with an American market output of 385 hp and 384 lb-ft of torque. It uses a 9-speed automatic and comes with Mercedes AWD goodies.

The S4 strangely doesn't have the cosmetic updates of the new model year, not that would have made any difference to the acceleration of the car. The 3.0 TFSI under the hood is a single-turbo V6 with 349 hp and 369 lb-ft of torque, delivered through an 8-speed to the quattro AWD system. And finally, there's the M340i, motivated by a Supra-like inline-6 turbo with 382 horsepower.

It wouldn't be a Throttle House video without a little banter. Apparently, James just bought that very S4 and is very happy about it. So, naturally, his co-host decided to show him that it's the slowest car in the segment. "He's going to go crying at the end of the day," Thomas notes.

Let's find out if that really is the case. The M340i wins the first race quite convincingly and the S4 keeps up just fine with the more powerful C 43. And in the second race... Thomas launches the car in reverse after talking a big game. Once the Steptronic is finally in drive, not reverse, the BMW wins the other races convincingly.
