BMW's twin-turbocharged 3.0-litre diesel came a very close second, with Audi's 2.0-litre TFSI engine third. But VW's TSI unit was just too good for them, impressing all of the 64 judges from 32 countries that made up the panel. Chairman of the awards, Dean Slavnich, said: "the fact that it wins both the overall award and our Best Green Engine prize indicates that you can have performance and efficiency in one package."
