What Car said.
Built at Hams Hall in Warwickshire, this engine features Valvetronic technology and VANOS valve control. The VANOS system decides when the engines valves are opened while Valvetronic determines by how much they open. The end result is improved engine performance in terms of power, economy and responsiveness. The Valvetronic 2.0-litre is in fact one of BMWs more impressive units and the generous spread of torque means that it drives a whole lot bigger than its modest capacity would at first suggest. Plumbed into the front of a Z4, this engine will propel the car from zero to 60mph in just over eight seconds and will run on to a top speed of 137mph. Do you really need a car that will travel significantly quicker than this? The answer is probably no. Yes, more power is always nice to have but, as sales of the larger capacity Z4 engines have shown, the vast majority of customers dont seem to view outright horsepower as a key selling point.
This bodes well for the Z4 2.0-litre. Few customers taking one for a test drive will feel that the 200Nm of torque is in any way inadequate.
