Here’s the story of the most important burble (yes, that is the collective noun) of MGBs to ever leave the factory in Oxfordshire. This gorgeous MGB factory lightweight is one of three BMC Competition Department cars campaigned at North America’s greatest endurance race, the 12 Hours of Sebring in 1964. No.48 was one of the very first MGB’s shipped to the States and kickstarted Blighty’s’s most lucrative sports car export, ever. Over the next two decades around 400,000 MGB would be built, with 9 out of every 10 cars being sent to eager MG fanatics in North America.


In 1964 MGBs had only just found their way onto American forecourts and a good class placing at Sebring would be essential to get sales booming in BMC’s most important export market. MG’s top brass instructed its best boffins to modify a trio of standard-spec LHD MGB Roadsters (already painted red, white and blue) and a host of performance goodies were rushed over from Abingdon to give the motors the full Works treatment. Plastic windows, aluminium door skins, lightweight bonnets, boots and wings were bolted on, as well as recessed grille lamps, fibreglass hardtops, bullet mirrors and Lexan headlamp covers – classic ‘Café Roadster’ inspiration.

The 140bhp 1798cc four-pot engine received new pistons, revised porting and custom camshafts, side-draft Weber and a close ratio four-speed box . These were fed by twin fuel tanks to improve range over the 12 hour endurance race and tri-speed windshield wipers were added in readiness for the expected downpours. The MGBs got off to a good start when the flag was dropped – their main rivals being a pair of Works Porsche Carreras – and the strategy was prove reliability and outlast the highly-strung German machines over the next 12 hours. However, the team’s resolve was soon tested when, after just 15 laps, the white #46 car was forced to retire from a knackered diff.

As the long-distance enduro played out, the remaining red and blue MGs pressed on hard, working their way through the orders. After a gruelling 12 hours the plucky MGBs finished 3rd and 4th in class; the red car taking 17th overall and this blue #48 car taking 22nd; a very good placing for the newbie British roadsters. Just 10 days after Sebring this pale blue MGB was auctioned off to an novice racer, who had fallen in love with this car as a Sebring spectator, for a little over $2,000; the cash-strapped chap had to use it as his daily driver over the next two years to get by. Little did he know that by 2015 that same Sebring veteran would be worth $88,000 when it was sold at Sotherby’s in May 2015. A ruddy bargain I reckon.

However, if you’re a Scalextrics fan, and you plan to hold your own 1:20 scale 12-hour enduro, then here’s something just a little more affordable for your slot car collection:

    I am a bit confused by this. The racing team I was associated with in 1964 or 1965 was part of Globe Motors in East Bridgewater Massachussetts. They were an MG/Austin Healy dealership and the two owners Billy Davis and Hugh Grissom both races SCCA races. One of the MGBs raced at Sebring was put up for auction with MG dealers allowed to bid on it and our team won the bid. Susequently we raced the car in the Watkins Glen 500, I think in 1966. Unfortunately he spring clip holding the throwout bearing in the yoke fell out and the car was forcedto retire early in the race. I can’t remember how much we paid for the car but i am pretty sure it was a good deal more than $2,000 and the car was not used as a daily driver! After thee race we tore the car completely down and were bery impressed with the quLity of workmanship! Crank journals were machined to incredible tolerances, nuts, bolts, and screws were aircraft quality. There was no starter solenoid just a make/break foot operated switch. Much of the engine compartment wiring was routed through metal tubes, there was a backup ignition coil and a backup Lucas fuel pump. But the most shocking feature emerged when we unwrapped the foam padding on the roll bar only to discover that the bar was fashioned out of exhaust pipe…probably to save weight? Hopefully the team manager warned the driver not to roll the car before the race started.

    I own the original MGB ‘BMC works’ car that raced at Sebring in 1963 – license no. 6DBL. There were two MGB’s entered by BMC in their first ever race. 6DBL is the only surviving car. This was 1963, the year before this car above raced in 64. Your featured car was not run by the BMC works team as it was entered by the US importer. Both my car and this one seem to have the same Sebring race number 48 (if the pics above are accurate). Neither of the two 1963 works cars finished the race because of problems with their 3 bearing engines which were under tested.
