The Light Six was powered by a watercooled 2 L straight-6 OHV engine with an output of 45 bhp at 3600 rpm designed by Peter Poppe, which provided the Two-litre saloon a maximum speed of 60 mph (97 km/h).

[3] The engine clutch and gearbox assembly was mounted and supported at three points, the single one in front, the rear pair by horizontally U-shaped leaf spring attachments.

[3] The body was very light weight rattle free fabric bodywork built by Rover under licence from Weymann.

On the 27 January 1930 the Rover's third and successful attempt started from St Raphael on the Riviera and ended at Calais 20 hours later, averaging 38 mph over 750 miles.

[citation needed] Tested by Autocar in late 1929 the car seemed capable of a 70 mph top speed though weather conditions prohibited a formal measurement.
