GM boss says hybrids push up prices
'GM will lose money on hybrids,' he said. 'We will continue to build them - and the cost will be spread across other cars.'
Lutz also said he thinks hybrid cars will never make up more than 10% of the US market. In the UK, hybrids make up 0.8% of car sales, according to figures from the Society of Motor Manufacturers and Traders.
GM will start to sell its first extended-range electric vehicle, the Chevrolet Volt, next year.
What other manufacturers say?
Toyota – the biggest maker of hybrids – disagrees with GM's stance on such cars.
A spokesman said: 'We will strive to make a million hybrids a year and as we achieve economies of scale, hybrid prices will come down.
'Hybrid vehicles are more complex, so there is a premium over non-hybrid vehicles, but we believe the overall cost of ownership, with the lower running costs, outweigh the initial purchase costs over non-hybrid cars.'
