- 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.

 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!
