Toyota has announced that its Avensis will now have two new 2.2-litre D-4D diesel engines.

The first of the two new diesels to reach the UK market will be a 148bhp 2.2 D-4D unit. This uses a second generation common rail system, reaches 0-62mph acceleration in 9.3 seconds and has a combined cycle fuel consumption of 47.1mpg.

The second phase of the new diesel engine development will come in early 2006 with the introduction in the UK of a 175bhp version of the 2.2 D-4D that will launch Toyota’s new concept for diesel engines, Clean Power.

According to Toyota, the 2.2 D-4D Clean Power has the lowest combined NOx and PM emissions of any production diesel engine. At the same time, the engine also offers 175bhp and 400Nm between 2,000 and 2,600rpm; the lowest levels of noise and vibration and on average 20% lower fuel consumption than engines of equivalent power output.

The two engines are being introduced together in other European markets, but in the UK their launch is to be separated with the more powerful 2.2 D-4D Clean Power engine set to join the Avensis range later.
