Jabbeke XK120 record
Dewis was the test driver who, on 20 October 1953 at Jabbeke, Belgium, drove a Jaguar XK120 to 172.412 mph, a record for production cars. The car had several aerodynamic modifications, including a distinctive bubble-shaped, air-tight canopy from a glider aircraft. After the record run the Jaguar XK120 was converted back to a road car and sold by the company.

XJ13 crash
On 21 January 1971 at the MIRA high-speed circuit Dewis drove the only Jaguar XJ13 for a film promoting the new V12 Jaguar E-type. Despite a damaged tyre, and against the instructions of Jaguar Director, Lofty England, the car was driven by Dewis at high speed. The tyre failed and the car crashed heavily, almost destroying it. Dewis was unharmed. The wreck of the car was put back into storage.

Work for Jaguar in retirement
In 2014 Dewis was still attending events related to Jaguar and giving talks about his work for the company. In June 2016 he appeared on the BBC's Top Gear TV show with the Jaguar F-type SVR.

Honours
In the 2015 New Year Honours Dewis was invested as an Officer of the Most Excellent Order of the British Empire (OBE) for services to the Motor Industry.
