Vauxhall's Ampera electric vehicle has been hailed as "a massive step for alternative-fuel cars" as it claimed What Car? Magazine's Green Car of the Year title.
Chas Hallett, the magazine's editor-in-chief, referred to the Ampera's low emissions and potential car insurance savings when he said the model delivered "all the benefits of owning an electric vehicle with virtually none of the drawbacks".
"It gives motorists the ability to dramatically reduce their emissions without changing their lifestyle, which is exactly what green cars need to do," he said.
The Ampera led an impressive line-up of vehicles honoured for their green credentials - among them the Kia Picanto 1.0 1 Air in the supermini class and the BMW 3 Series 318d in the executive car category.
Volkswagen Golf Bluemotion won the best green small family car award and Ford's Mondeo the green family car prize, while the fun car award went to the Mini 1.6D Cooper.
Renault's Scenic was named the best green MPV and the Peugeot 3008 2.0 HDi Hybrid4 - the world's first diesel hybrid - claimed the SUV title.
