The final product, the MG F, was finally unveiled on 8 March 1995, [2] and went on sale in September that year with a 1.8 litre 120 bhp engine, and was joined several months later by a 145 bhp VVC (variable valve control) version. It was hugely popular and received plaudits for its excellent ride and handling.

There are two engines available, the 1.8i K-series 1796cc 16v and the 1.8i VVC (Variable Valve Control), with power figures of 118bhp and 143bhp respectively which give a 0-60 time of 8.5 (1.8i) and 7.0 (VVC) seconds.

How the MGF VVC engine really works… "Power output is finally dependent upon weight of air efficiently burnt per minute, and this in the end is fixed absolutely by the breathing power of the valve gear. In detail the gas flow will depend on the area of the valves, the lift, and the time during which they are open."

Spotting the difference between a VVC and a non-VVC MGF: With the availability of second hand VVC style five spoke wheels (Mk1) or the ability to specify VVC-style 16" 6-square spoke wheels on MY2000 cars, and the relative lack of outward identifying features between cars equipped with the VVC or not, it is sensible for a potential purchaser of ...

2015年4月2日 · It seems that people almost always recommend a VVC over an Mpi-powered MGF but is there really that much difference between the two in performance? Are there other differences between the two that make the VVC that much more of a desirable car? My '03 Corolla has a VVC engine but I'm certainly not excited about the car

2008年11月4日 · My 1996 MGF VVC 1.8 has erratic idling problems, and it's not throttle body or coolant sensors. It can be idling quite happily, and then mysteriously raises to 2100rpm for a while. Also, the cooling fans come on almost straight away after starting the engine. I suspect it's the ECU getting muddled up, and even a dealer confirmed this.

The VVC demonstrates the engines leap in overall efficiency and ability to have both added top end power and good lower rpm operation with an average of 37mpg. These figures are all compared with using like testing conditions to provide a realistic comparison.

2016年9月13日 · See if there is a cambelt on each end of the engine. If so, is definitely a VVC. Also, there is a VVC hydraulic control unit on the inlet side of the head (right side of the car) about 4-5" high. Other ways to check are: Does it actually rev to the 7250 rpm limit as the MPI is redlined at 6750 and hits the rev limiter shortly after.

The MGF was released in two variations – the standard 1.8i and the VVC (released in March 1996) giving differing power levels but largely the same trim. They all came with remote central locking and dead locking, volumetric and perimetric alarm system, heated door mirrors and electric windows, The VVC had additional high level rear brake ...
