The straight-six in an X3.
The xDrive35i puts the N55 into the more upright X3. Compare it with the 535i to see how seating position, body shape and four-wheel drive change the car around a familiar engine.
An upright family BMW with six-cylinder power.
An SUV adds height and mass to the driving experience.
The 35i badge in this record belongs to a turbocharged straight-six.
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.
