Small coupé, substantial engine.
The two-door M235i combines a compact coupé body with the N55 straight-six. It is an M Performance model, so its badge describes a different place in the range from the full M2.

Rear-seat access comes through the front doors.
The two-door M235i and four-door M235i Gran Coupé use different engine layouts.
N55 · Inline-six
A 2,979 cm³ inline-six with one twin-scroll turbocharger, direct injection and Valvetronic.
N55 in a 2013 X5 xDrive35i. Engine-family reference; covers and installation differ across applications.
Same family. Different application.
This model uses a longitudinal 3.0-liter N55 inline-six. Its factory output and vehicle configuration are specific to the model and market shown.
Twin-scroll is not twin-turbo.
One turbocharger has two exhaust passages feeding its turbine. Exhaust energy spins the compressor, which supplies pressurized intake air. The turbo is largely hidden by surrounding hardware in this reference photograph.
Air in. Heat out.
Filtered air enters the compressor, then passes through charge-air cooling before reaching the intake manifold. The intercooler cools the air heated by compression.
Valvetronic & VANOS.
Valvetronic adjusts intake-valve lift. VANOS adjusts camshaft timing. They control different aspects of the valve operation; neither is another turbocharger.
