Mercedes Is Owning This Formula 1 Season. Here’s Why

We’re two races into the Formula 1 season, and Mercedes-Benz has been killing it. Now we know the team’s secret (one of them, anyway), and it’s brilliantly simple.

This year, the entire grid of 22 cars is running 1.6-liter turbocharged V6 engines with a sophisticated hybrid energy system that scavenges energy from the brakes and turbo. F1 engineers are among the sharpest on the planet, and they have thousands of parameters they can tweak and tricks they can use to make these power units as powerful and efficient as possible. Mercedes’ best and brightest found a particularly cool one: they essentially cut the turbo in half.

This is very smart. Here’s why.

What Mercedes’ boffins have done, according to Sky Sports F1 technical guru Mark Hughes, is split the turbo in half, mounting the exhaust turbine at the rear of the engine and the intake turbine at the front. A shaft running through the V of the V6 engine connects the two halves, keeping the hot exhaust gases driving the turbo from heating the cool air it’s drawing into the engine.

Aside from getting cooler air into the engine and extracting more power (maybe as much as 50 horsepower), this setup also allows Mercedes to keep drivetrain components closer to the center of the car. It also allowed the team to use a smaller intercooler, which cools off the heated air before going into the engine, compared to the rest of the cars.

And what about those other cars?

Even with Mercedes’ secret out, there’s not much anyone can do about it. Engine designs are essentially locked down for the season, so the only teams that can benefit from it are the teams using Mercedes-Benz engines. But those teams–McLaren, Williams, and Force India–haven’t been testing these new V6s as long as the official factory team. It’s rumored that Mercedes has been running a version of this engine in secret for almost two years, and even though it supplies engines to other teams, they are, after all, competitors. And now they’re on a steep learning curve as Mercedes continues to dominate the pack.
