Commonly reported ownership points, not a guarantee of faults. Always get an independent inspection.
A grand tourer with extra doors.
The 640i Gran Coupé combines a flowing 6 Series roofline with four-door access. Its turbocharged straight-six offers a different interpretation of the grand tourer from the V8-powered M6.
A stylish four-door grand tourer.
The low roofline matters when trying the rear seats.
Gran Coupé describes the body concept, not the number of cylinders.
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.
