The Powerful 1974 MG BGT V-8

The 1974 MG BGT V-8 is a rare car today in the United States. The automobile featured in this article is a V-8 that was built between 1973 and 1976 in a coupe model only.

British Leyland, formed in 1968, announced in 1973 that this new Pininfarina designed body offering would be powered by a lightweight aluminum Rover 3.5 Liter V-8 engine that would have a top speed of 120 MPH with 137 horsepower.

This powerful aluminum engine weighed about forty pounds less that the previous cast iron four cylinder. This was a big move in as much as the engine would deliver about twice the power of the current model and with less weight. What was created was a new high power sports car.

It should be noted that a V-8 in an MG was showing to work out quite well based on earlier engine conversions done by mini racer Ken Costello. There is little doubt that this success led MG themselves to come out with their own V-8 product using the Rover engine. MG's engine however didn't deliver the 180 horsepower that Costello's did.

With the addition of the new V-8 British Leyland also made adjustments to the suspension, body and brakes and had to make adjustments as well to the inner wheel arches and engine bulkhead. The suspension changes were not major and had to do with the increase in torque. Most suspension modifications went to the rear.

New to the MG V-8's

The company promoted the comfort offered in the V-8 BGT in as much that they installed nylon upholstery which was to help keep a driver from sliding around. Also added to the car was a collapsible steering column which was for safety. Because U.S. law called for impact absorbing dashboards, the V-8 MG's had smaller tachometers and speedometers to fit in the larger steering column. This was not an issue at the time in the British home market.Other than the reduced size gauges on the dashboard, the interior changes from the MGB model were indistinguishable.

An optional item for the BGT's was a sunroof. This would have been installed at the dealer level.

The MG Evolution

A good many people believe that the MG BGT Roadster shown here had it's origins all the way back to a Belgian coachbuilder who produced the Berlinette MGB 1800 in 1964. It's thought that this automobile was used as the prototype for the factory GT's built afterward but it appears that the factory had a similar model on their drawing boards.  Only a bit over fifty of the Berlinette models were built therefore they didn't affect the factory's ongoing project.

The MG BGT model was discontinued in 1976 apparently because of a conflict with the Triumph Stag also produced by British Leyland. Reportedly, it was felt that the MG BGT was overshadowing the Triumph model.

Whether this was a good decision is arguable as were some other decisions made by the company. A case could be made that the Triumph Stage was not appealing to the same market. When the BGT was taken off the market the car was still very popular with the sports car public.
