About More-MPG

Who are more-mpg ?

www.more-mpg.co.uk (More Miles Per Gallon) is part of the successful THOR group of companies based in Coventry.

The THOR group consists of THOR Racing (modified performance car tuning), THOR Garage Services (maintenance, diagnostics and repairs of family cars,fleet and light commercials) and THOR Engine Tuning (dedicated engine tuning services with rolling road, bespoke modifications)

The THOR group of companies was established by Peter Betts and his wife Susannah back in 1996, so is owned and managed by a local family with a team of professionally trained staff.

The company has predominantly operated as THOR Racing for the past 7 years, dedicated to performance car tuning but since moving to new premises in Canley, Coventry the company has expanded its service coverage to general garage services.

With our pedigree in performance car modifications, circuit and drag racing and diagnostics we are able to offer customers the same skill, expertise and attention to detail in performing a simple oil change, service light reset to an engine exchange or rebuild. Rivalling the main dealer for quality and level of diagnostic skill yet also competing with other local garages on price.

Please take a moment to browse our Garage Services website and our Racing Website.
