MGBGTV8
profile
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 decades 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.
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 has been an undiscovered classic sportscar but since
2010 prices have risen substantially.
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!
