Why you’d want one

  • A modern, manageable sports saloon.

Know before you buy

  • Few systemic faults; keep to oil service intervals
  • Coolant and oil leaks on higher-mileage cars
  • Run-flat tyres make the ride firmer

Commonly reported ownership points, not a guarantee of faults. Always get an independent inspection.

The story

The 330i in the turbo-four era.

The G20 330i shows how the 3 Series changed: this record uses a turbocharged B48 four-cylinder rather than the straight-six found in the earlier E46 330i. The familiar badge tells only part of the story.

Best for

A modern, manageable sports saloon.

Trade-off

Check equipment and market specification rather than assuming from the badge.

A modern 330i badge does not mean a 3.0-litre engine.

Under the bonnet

B48 · Inline-four

A 1,998 cm³ turbocharged inline-four with direct injection, Valvetronic and Double VANOS. This selection uses the European B48 specification; US emissions variants can use B46.

Engine profile
B48 engine

B48 four-cylinder engine-family reference. Longitudinal and transverse installations differ.

Four cylinders in line.

The B48 family uses four cylinders and one twin-scroll turbocharger. The museum cutaway exposes internal components, but is not the exact G20 revision.
