In the new BMW 3-series lineup, the 335i Luxury is the sole model to maintain six-cylinder power, at least for the time being.

Horsepower & Torque for the BMW 335i
From 2007 through 2015, the BMW 335i was a viable option. The N54 and N55 were the 335i’s two main engines. The two engines each have a 3.0L inline-6 turbocharger. The N55 engine only has a single twin-scroll turbo, whereas the previous N54 engine uses two turbos. Despite having different turbos, the majority of BMW 335i vehicles produce the same 300 hp and 300 lb-ft of torque. In this post, we analyze the horsepower and torque of the 335i according to various periods and talk more about the cars’ potential horsepower.

The N54 was introduced in the 335i model of the E90/E91/E92/E93 3 Series lineup during the 2006 Geneva Motor Show.
