MG 'J' Type Background

Following the success of the 'M' type Midget, there appeared in 1932 the lovely little J2.  Costing £199.10s and with an 850cc engine, it looked as if it really meant business.  It's spartan 2 door body, slab tank, fold flat windshield, door cutaways and octagonal dash instruments set MG design for the next 20 years.  The stark and sporting 'cycle' type mudguards soon gave way to sweeping wings and running boards.

The J3 was an open sports 2 seater.  750cc and supercharged.

The J4 was a racing car and did not appear until 1933.  The delay was due to the existing 8 inch brake gear which was not sufficient for such a fast car and new gear had to be prepared.  A new system was being developed for the 'L' type (a larger 6 cylinder MG).  This was 12 inch and proved adequate for stopping the J4 quickly.  It should be noted that a J4 was capable of 120mph from a 750cc engine!

Notable racing successes, mainly in the hands of the greatest exponent of the day Hammy Hamilton were many.  Purchasing the first J4 in the spring of 1933 (the same month as the greatest of all MG's the K3 Magnette arrived on the scene), Hammy put it on a train to Nurburg, Germany and won his class and broke the lap record in the Eifelrennen.  Probably his greatest achievement in the J4 was the 1933 T.T.

Nuvolari, one of the all time aces was in a K3 and had a 3 hour dog-fight with Hammy, each repeatedly breaking his lap record, until Hamilton, having stopped for fuel on the final lap, finished forty seconds behind Nuvolari, who crossed the line with a dry tank.  Hammy's average speed for the race 73.46 mph.

Also in 1933 two other versions of the J type appeared, the J1 four seater and the sliding roof salonette.
