Michelotti Mini – MG ADO70

After rejecting the ADO34 and ADO35 projects to put the MG name on a Mini based vehicle in 1966 the conglomerate known as British Leyland Motor Corporation Ltd since 1968 re visited the idea of building a Mini based MG in 1970.

Project code ADO70 also known as the Michelotti Mini seen here is based on a 1275GT chassis and running gear a model which had been introduced in 1969.

The only mechanical modification to the car was the fitting of twin exhaust tail pipes.

Paul Hughes at the BLMC Longbridge works was responsible for the split Targa top styling and when the drawings were complete another member of the design team Robin Owen drove the new Mini 1275GT with it’s twin tailpipe modification over to Studio Tecnico Carrozzeria G. Michelotti in Turin, Italy

For two months Robin oversaw the removal of the original bodywork and it’s replacement with the new design at Michelotti.

On returning the Michelotti Mini to the UK it was immediately apparent that the new body was too heavy and that the twin tailpipe modification was insufficient to make for the lost performance, or to warrant putting the car in production with an MG badge.

New safety and emissions legislation in the USA were also responsible for halting any further development of the ADO70.

Thanks for joining me on this “Michelotti Mini” edition of “Gettin’ a li’l psycho on tyres” I hope you will join me again for Mercedes Monday tomorrow. Don’t forget to come back now.

The Gearless Green Car – Mini 9X ADO20

Today’s featured British Leyland Motor Corporation Mini 9X test car was built to trial the replacement overhead cam engine intended to replace the BMC ‘A’ series push rod that had been introduced in 1951 along with the Austin A30, and a new gearless transmission.

The single overhead cam eight valve four cylinder engine has a capacity of 1500 cc / 91.5 cui with a rubber belt driving the cam, when tested it produced 50hp at 4000 rpm.

Despite achieving only 20 hours running time over 4 and half weeks on a test bed in 1975 due to leaks and other faults this car was regularly driven up until 1987 with only a cam belt failure on the M5 in 1982 during high speed testing.

The transmission consists of a torque converter and a mechanical final drive sourced from an Austin Allegro, the only gear options being forwards or reverse.

Other novel features on the 9X test cars were a redesigned nose, vertical strut suspension, this car was also fitted with competition aluminium doors, with sliding windows and original ADO15 type exterior hinges and boot lid, the unique bonnet and wings were also in weight saving aluminium, the original doors and boot lid corroded and have been replaced by steel items.

Four ADO20 Minis were converted to house the 9X transmission three of which also had the 9X single overhead cam engine also fitted, today’s example seen at the Atwell Wilson Motor Museum, Calne, was the second to be converted and the first to be fitted with the 9X engine, known at the factory as The Green Car, originally painted Connaught Green, resprayed in 1985 to the current Tundra Green, it was purchased in 1975 by the father of the Mini Sir Alec Issigonis who used it as his preferred transport for many years until he sold it back to Austin Rover as BLMC had become.

One prototype to an all new 9X design featuring the overhead cam engine, gearless transmission, front strut suspension and hatchback tailgate was built before the project was cancelled leaving the Mini in production until 2000 having out lived it’s eventual successor the Austin miniMetro that was in production from 1980 to 1997.

Federal Spec – MG Midget 1500

Today’s blog is a little thank you to peteran51 whom I know as Piet who a couple of weeks posted a link to one of his favourite cars the #238 Frank Hernandez Austin Streamliner on the Spridget Register website www.spridgets.net in Germany.

The British Motor Corporation MG Midget started out life as a badge engineered Austin Healey Sprite MK II in 1961 reviving the successful Midget name which MG had used in the 1930’s.

By 1972 the Midget had completely replaced the Sprite in the now British Leyland Motor Corporation model line.

This 1979 version is powered by a 1493cc / 91 CUI motor taken from the Triumph Spitfire with a modified 4 speed all synchromesh gearbox from the Morris Marina.

Production ceased on 7th December 1979 making this particular vehicle registered in 1979/80 in Reading one of the last of the 73,899 Midget 1500’s that had been produced since 1974.

Midgets today are still raced regularly with dedicated Midget series in the UK which has been running since 1977. Parts are still available thanks to British Motor Heritage which owns original press tools sufficient to supply complete Midget body shells.

My thanks again to Piet for the heads up, I hope you have enjoyed today’s US Federal bumper spec edition of Gettin’ a lil’ psycho on tyres and that you will join me again tomorrow for something that I will photograph at a Piston Heads Sunday Service later this morning. Don’t forget to come back now !

PS It’s sad to report that Psycho on Tyres contributor Ed Arnaudin, who took all of the late 50’s sports car photographs it has been my humble privilege to share this past couple of months is not very well, I hope you will join me wishing him a full and speedy recovery.
