BMW 320si

[Deep Dish]

Satt nettopp å så på Fifth Gear, og der gir de bort den nye BMW 320si, en limited edition utgave.! Hvorfor kan ikke AutoFil ha slike konkuranser.!!!

Her er litt info om BMW 320si (gadd ikke oversette)

Designed to comply with FIA homologation regulations, only 500 BMW 320si’s are destined for the UK out of 2,600 cars worldwide. All feature a hand-built four-cylinder engine made at BMW’s engine plant at Hams Hall, near Coventry. The high revving 2.0-litre unit delivers 173hp at 7,000rpm (before reaching its red line at 7,300rpm) and 200Nm of torque at 4,250rpm.

This engine powers the BMW from zero to 62mph in 8.1 seconds and, if left unchecked, onto a top speed of 140mph. Although inspired by the racetrack, the car still delivers 31.7mpg on the combined cycle and conforms to the EU4 emissions regulations.

The limited production run of the BMW 320si starts in March 2006 and ends in September 2006, with first customer deliveries expected in April 2006.

This high level of performance has been achieved using BMW’s motorsport technology. Compared with the ‘standard’ BMW 320i, the engine has been significantly modified with larger induction and exhaust valves to increase airflow. The cylinder bore has increased by 1mm to 85mm while the stroke has been reduced by 2mm to 88mm.

The compression ratio of the engine has also been increased from 10.5:1 to 11.0:1, helping to boost power by 23hp over the 320i. Additionally, instead of running with grey-cast-iron cylinder liners, the pistons run in special aluminium-alloy liners in the cylinder block. Engineers have also decided to remove BMW’s patented VALVETRONIC induction system, reverting to a conventional throttle due to the higher engine speeds demanded by a racing engine.
