MGBGTV8
- the
MG with effortless performance |

Launched in August 1973, the V8 powered MGB combined the popular fixed
head coupe body style with a powerful three and half litre light alloy V8 engine.
The Rover powerplant ran with a reduced compression ratio but an increased torque
compared with the similar engines then used in the Rover saloons. The result transformed
the MGB, creating a very nimble car with the luxury of multi-cylinder power which
is both flexible and economical - features which continue to have a special appeal
for V8 enthusiasts today! On the road the MGBGTV8 has an effortless
performance, accelerating rapidly in the higher gears with 125 mph available in
both direct and overdrive top. Hills just melt away and the torque gives the car
an unfussy manner. The 0 to 60 time of 7.7 seconds is still over 35 years later,
a time many of today's sports saloons cannot touch. Even when asked to work hard,
the exhaust note retains its very pleasingly modest but purposeful burble in keeping
with its understated manner. The V8 engine, although from an old Buick
design from the early fifties, contains hydraulic cam followers which give the
MGBGTV8 a quietness that compliments the smooth power. Under the bonnet, the lightweight
aluminium V8 engine seems much bigger than the original four cylinder steel engine
but is only just a little heavier when the engine ancillaries are included. The
lightweight benefits are good front to rear weight distribution and an appreciable
increase in the power to weight ratio, even from the detuned 137 bhp V8 power
unit. A surprising
feature of the MGBGTV8 is the fuel economy. Even driven on the open road with
a sense of fun the enthusiast can enjoy with V8 power, it is quite easy to achieve
between 27 and 31 miles to the gallon. The overdrive unit gives the MGBGTV8 long
legs with around 29 mph per 1,000 rpm or 3,000 rpm at 90 mph. The convenient overdrive
facility is available on top gear at the flick of a stalk switch on the steering
column and on many of the earlier chrome bumpered examples of the model, it is
available on third gear as well. The
MGBGTV8 is however not without its poor features - excessive wind noise at speed
and a choppy ride at slow speeds from the stiffer rear springs which are needed
to cope with the higher power output. The gearbox has to be treated with consideration
when punching the additional power through to the road wheels. | MGBGTV8

At its launch in 1973, the MGBGTV8 was welcomed as a powerful example of
the MG marque but generally regarded as arriving several years late in a popular
but ageing bodyshell and suspension package, then over ten years old. The MGBGTV8
is very much an MG combining the famous marque's Safety Fast! features - speed
and performance with predictable and forgiving handling characteristics. At the
time of the launch, the specification of servo assisted brakes, tinted glass,
distinctive light alloy wheels, fine cord covered adjustable seats, two speed
wipers and an overdrive as standard made it a refined sports car for 1973 and
good value at its launch price of £2,294. In so many ways the MGBGTV8 is
an undiscovered classic sportscar and prices have never been driven up by "chequebook
investors". It remains a sports car that a small band of enthusiasts
enjoy and see as very good value today in every sense. It is much liked by MG
enthusiasts! See
