However for the average family car or SUV, diesel seems to have taken over, again for obvious reasons.

exactly, take money out of the equation, and petrol wins hands down.

very much so, for Lemans, the rules are:
Naturally aspirated engines limited to 3400 cc (207.5 ci). Turbochargers and superchargers allowed for petrol engines with a maximum displacement of 2000 cc (122 ci) and for diesel engines with a maximum displacement of 3700 cc (225.8 ci), restrictor-limited to around 700 bhp. No limits on the number of cylinders for any type of engine.
so, you have NA petrol at 3.4L, turbo petrol at 2L or Dismal turbo at 3.7L
that's called parity.
Yes, back to BMW, the new 335d engine is good, however, looking at the numbers, it's 'power band' is basically 1,000 revs wide, great match to the 8 speed box mind.
