Last year GM took a 9.5 percent share of the European new car market the carmaker's highest since 1999.
Opel/Vauxhall sales were up 4.3 per cent, while Chevrolet sales were boosted by 33.6 per cent and Cadillac sales rose 30.9 per cent.
Carl-Peter Forster, GM Europe President, said: Our multi-brand strategy is beginning to make an impact, as is an aggressive strategy for growth in Eastern and Central Europe. Importantly, these results show how quickly GM has embraced growth in the new markets of Europe.
The UK, Russia, Italy, Ukraine and Greece were the main contributors to GM's growth in 2007.
