Boasting the world's best engine, the 135i Coupé has additional bragging rights in the form of its 225kW Twin Turbo straight-six guise of the award winning powerplant.

Coupled with the slender figure of the 135i Coupé, the dash to 100km/h takes just 5.3 seconds from a standstill, helped dramatically by a healthy 400Nm on tap between 1,300rpm and 5,000rpm.

Accompanying the 135i Coupé in the spotlight will be BMW's second twin turbo Australian debut with the most powerful diesel BMW has ever offered in Australia - the 200 kW 3.0-litre straight-six twin turbo X5 3.0sd.

The engine has been tuned to deliver sustainable performance, with a mammoth 565Nm ensuring sportscar style acceleration yet returning an amazing 8.8 litres/100 km on the combined cycle.

Acceleration belies its SUV appearance, with zero to 100km/h done away with in 7.2 seconds, and an ample top speed of 230km/h.

Also making their Brisbane début from BMW are the high-revving 309kW BMW M3, the updated 270kW V8 4.8-litre 6 Series Convertible and the latest generation of four-cylinder diesel models.
