Silent Running Hypoid Gears – Chrysler Six C7 Airstream Rumble Seat Convertible

Visitors to the 1934 New York Auto Show were stunned by the appearance of the Chrysler Airflow with it’s aero dynamic shape and the comfort promised by mounting the engine over the front axle and moving the rear seats ahead of the rear axle.

Unfortunately, not for the first time nor the last, the futuristic Airflow did not sell as well as might be expected, despite it’s superior agility and comfort, so subsequent Airflow models became more conservative in their design.

The 1936 Chrysler Six C7 Convertible seen here is powered by a 241.5 cui / 3,957.5 cc flat head straight six, who’s origins can be traced back to 1924, with an automatic choke ensured easy starting.

A new rear axle which promised silent running thanks to it’s hypoid gears, a spiral bevel gear whose axis does not intersect with the axis of the meshing gear, was introduced to the 1936 C7 range with automatic overdrive an option to further reduce the vehicles noise at speed.

Only 450 Chrysler Six C7 Airstream Rumble Seat Convertibles, which cost nearly double that of the equivalent Ford, are believed to have been built,

The rare right hand example, seen here at Summer Classics Easter Compton, almost certainly a conversion as the speedometer is on the passengers side, is showing as first registered in the UK on the 1st of April 1994, it is also showing as having a 2.7 litre 167 cui motor, a detail I suspect is at variance with the facts since there was no Chrylser 4,6 or 8 cylinder motor of that size that I know of, if you know different please do not hesitate to chime in below.

Entirely New ? – Chevrolet Bel Air

Back in the 1950’s it would appear manufacturers could not keep up with demand for new innovations and so would resort to upgrading older chassis with restyled body panels and selling them as entirely new, such was the case with the 1953 Chevrolet Bel Air which was advertised with the strap line ‘Entirely new through and through’ which actually shared its chassis and running gear with the Bel Air built from 1950 to 1952.

Today’s featured car appears to have been built in 1954, the last year in which the first generation Bel Air’s were built.

During the last years production all of the 3,345 lb Bel Airs are said to have been fitted with a 125 hp 3.9 liter / 235.5 cui straight six ‘Blue Flame’ motor.

The original concept for the Bel Air was to style a hard top vehicle to look like a convertible, to confuse the issue Bel Air’s were originally available as either 2 door hard top coupé, 4 door sedan, 2 door convertible or 4 door Station Wagon / Estate.

This particular Bel Air is used as a support vehicle by the Gas Racing drag team who run the Pinto powered slingshot coupé Old ‘n’ Gold for drivers Scottie ‘Dog’ Durrant and Gina ‘Hot Rod’ Rumble.

According to Facebook Gina was recently recorded a 12.95 ET run in Old’n’Gold.
