Just checked; it's a 2.0 bi-turbo diesel probably very similar to the 204ps T6 unit.Not wanting to look a tit before posting that, I looked at the configurators to double check what I thought. Granted I only looked at Passat estate, but the config did not give a petrol option.
Many berate BMW but at least they stick to RWD (except that darned active tourer thing), still use big engines and still have plenty of petrol options.
