Elva Courier Sebring T-Type

Developed for those who require advanced specifications for National and International Events, the ‘T-type Sebring’ offers an unique combination of recognised racing features at a realistic price. The model has been developed from the normal road going Mk. IV T-type but offers a lightweight body shell and chassis plus a number of additional features as listed below:

Either Ford 122E or MGB units according to customer’s requirements. These engines are supplied either in standard form or in various stages of tune up to 140 b.h,p. as shown on the extra equipment  schedule.

Chassis:

A special lightweight chassis has been built for this car. It is identical in layout to the normal T-type chassis but in addition has adjustable rear wishbones and alternative spring and damper specifications according to the type of event for which the car is intended.

Body:

A lightweight body has been built of a special glass-fibre matt to give maximum strength where required and glass-fibre doors replace the steel ones normally used on the T-type.

Differential:

A limited slip differential is available and alternative ratios will be supplied according to circuit requirements.

Fuel System:

Twin Bendix fuel pumps transfer the fuel from the special long range tank behind the driver’s seat through large bore piping to the carburettor.

Oil Cooler:

An oil cooler is fitted as standard equipment.

Wheels and Tyres:

14″ wire wheels with 6L rims are fitted with knock off hubs. Dunlop racing or 5.P tyres are fitted according to requirements.

TWO YOUNG AMERICANS PROVE LE MANS IS STILL 'A LA CARTE' - IF YOU REALLY TRY

Lutz and Osteen to Drive Privately Entered M. G.B. Powered Elva Courier

Two young Americans, Ronald Lutz and Dick Osteen, have achieved the almost impossible –  they’ve succeeded by sheer enthusiasm, determination and hard work in getting as far as first reserve for their privately entered M.G.B.-powered Elva Courier in the 1964 Le Mans 24-hour race this weekend. 

Having passed the scrutineering with all its attendant homologation horrors and with only the practicing sieve to go through, they are confident of realising the dream of many amateur sports car racing enthusiasts of competing in this classic event. 

Lutz and Osteen, who are attached to the U.S. Services in France, have raced on many Continental circuits and in the States. Together they have carried out a number of modifications to the Elva Courier specification car they obtained from the manufacturers, the Lambretta-Trojan Group of Croydon, Surrey. These include nose extensions for slipstreaming and a glass fibre hardtop they developed themselves. 

Commenting on their entry, Lutz said: “Dick and I have been burning the midnight oil for quite a spell getting the car ready and it looks as if we’re going to prove that you don’t have to be a world champion with an all that well-known a car to get a ride in this great race”

Note: Elva-Porsche sports racing cars have had considerable success in the States and on the Continent this year,most recent being the winning of the Alpen-Bergpreis Rossfeld event – the Rossfeld Fill Climb – by Edgar Barth in an Elva Porsche on June 7, which counts towards the Grand Touring Car Manufacturers Championship and the European Mountain Championship. The new 2-litre Elva-B.M.W. is now also being exported to America after having been driven with equal success by Tony Lanfranchi in the U.K. races this season.
