Fluence, Renault's latest concept car, is an upmarket, four-seater sports coupé.

It was presented at the Louis Vuitton Classic concours d'élégance held for the first time at Waddesdon Manor near Aylesbury, instead of its traditional home of the Hurlingham Club in London.

Fluence is a 4.60-metre long coupé, company insiders say that the Fluence could be the next generation Laguna as it is comparable in size in the current Renault range.

Its design continues the latest theme from Renault’s Design department, started with the Wind concept roadster in March.

The front-mounted 3.5 litre V6 petrol engine develops 280bhp. Renault says the “suspension and chassis allow a fast and agile driving style that adapts to all road conditions.

“Fluence is as much a pleasure to drive as a top-of-the-range saloon, while its six-speed automatic transmission with flick-shift control adds to driving comfort and serenity”.

Strictly a concept, Renault has no plans to put Fluence into production, but its design will heavily influence other new Renaults in the next two or three years, the company says.
