Flat-four with alloy heads and twin carburettors, rear springs underslung, automatic clutch (but no synchromesh) to four-speed 'box. Early fastback Jupiters and Jasons had slant radiators which didn't help servicing, so more vertical rad and 7 HP saloon body on Plover (March onwards) with steel-spoke instead of wire wheels. A few older-type saloons (Peregrine) also with this later footwear.
