BMW has restyled the rear of its BMW Z3 roadster and is making engine changes, creating a new entry level model, which should be introduced by the summer. The current entry model, the 140bhp 1.9-litre, will be replaced by a 2.0-litre 150bhp six-cylinder unit.

The new entry level model is a 1.8-litre 118bhp four cylinder engine. Exterior changes include recontoured rear wheel arches, restyled boot lid, L-shaped light clusters and new rear bumpers.
