Rover KV6 engine
The KV6 automotive petrol engine has a 24-valve quad-cam V6 configuration, and a pressurising variable-length intake manifold to add hot spots throughout the rev range. Variants exist in 2.0 to 2.5 litres (1,997 to 2,497 cc) capacities. These were built initially by Rover Group, then by Powertrain Ltd (a sister company to MG Rover). KIA manufactured KV6 in Korea under licence. Production moved from the UK to China in 2005, re-designated NV6.
First introduced into the Rover 800 series with the 1996 facelift, including the flagship Sterling saloon and coupe models, it has since also powered the Rover 75 and its sister car, the MG ZT, as well as the Rover 45 and the MG ZS.
The engine was designed and developed by Rover at Longbridge to replace the Honda 2.7l V6 engine which was about to become non-compliant with tightening emissions legislation. The original unit was designed for low volume production but was later redesigned to fit into the smaller Rover 75's bonnet, although performance remained similar.
In 2004 the engine was licensed to Kia Motors who invested in a new plant at the Asan Bay complex to build the engine. This engine was used in several Kia vehicles. Its introduction in Korea shortly followed its use by Rover in the Sterling.
The NV6 variant is deployed in Roewe 750 and MG 7 cars (China).
At introduction, the engine enjoyed considerable technological advancement compared with its competition,[citation needed] most notably being the lightest and shortest V6 in its class.[citation needed] It has fully automatically tensioned drive belts and adaptive Siemens EMS2000 engine management. The fuelling and ignition timing are constantly varied to match the load on the engine to improve refinement. The engine uses Variable Geometry Induction, whereby air induction pipe lengths vary to optimise engine torque in response to different engine and road speeds, aiding refinement and efficiency. Although it bears the name of K Series, the engine has almost no components in common with the 4-cylinder version.
In its Rover setup, the unit delivers peak engine power of 175 PS (129 kW; 173 hp) at 6,500 rpm, and maximum torque of 240 N⋅m (177 lb⋅ft) at 4000 rpm. The automatic gearbox in V6 800s is able to communicate with the engine, briefly easing torque to allow smoother changes.
A noticeable feature of the engine is its quietly growling engine note.[citation needed]
