The new Renault Laguna Coupe will cost from £20,995.
Renault is pitching the car against rivals from Audi, BMW and Mercedes, saying it offers similar levels of performance and refinement for considerably less money.
Buyers have a choice of four engines at launch: 147bhp and 176bhp 2.0-litre diesels, and 201bhp 2.0-litre and 235bhp 3.5-litre petrols. A 230bhp 3.0-litre diesel engine will be available early next year.
Standard equipment includes 18-inch alloy wheels, an MP3 CD player, eight airbags, automatic lights and wipers, climate control, rear parking sensors and xenon headlights.
The Coupe GT trim level adds four-wheel steering, an automatic parking brake, electrically folding door mirrors, leather upholstery and keyless entry.
Buyers can also upgrade to an optional BOSE stereo, sat-nav, heated front seats and a tyre-pressure monitor.
The first cars will be delivered in January.
