BMW M4 Races M5 In Drag Battle Of Tuned Performance Cars

Modern performance BMW models are known for showing conservative output figures in the books. Or, in other words, there is a hidden potential that can be easily unlocked through simple software. But how much power can be added to the stock BMW M4 without hardware modifications? Can it beat a tuned M5? Let’s find out.

New video from Drag Time showed off the new BMW M4 xDrive Competition, which underwent software tweaks to release more power. The clip begins with a comparison between the car’s quarter-mile times with and without the new software. The more powerful version runs in 10.826 seconds versus 11.305 for the stock version. That’s a pretty nice improvement considering it only needed new software to achieve it.

Midway through the video, it’s time for a drag race against a modified BMW M5 Competition. The pink performance sedan has a new exhaust system, new intakes and software tuning for an estimated peak power of around 750 horsepower (559 kilowatts). As a reminder, that power is channeled to all four wheels via an eight-speed automatic transmission.

In contrast, the M4 Competition offers a twin-turbo 3.0-liter inline-six with Dahler software, producing around 620 hp (462 kW). Again, power is sent to both axles via the xDrive system, mated to an eight-speed ZF sourced automatic. The M4 is lighter but less powerful.

In a series of three races, the M4 Competition clinched its first round victory by narrowly beating the M5 Competition. However, in the second race, the pink sedan had a much better start, which gave it a solid advantage from the start and the M4 was unable to catch up. It’s 1:1.

Which car took the overall win? Of course, we’re not going to spoil the entire video with this information. As a small hint, we can only say that both cars had a great start in the last laps and it was power and weight that decided the race in the end, not reaction time.
