The name pretty much says it all. That "L" in the title says you've got the extended wheelbase of a luxury limousine, the kind that stretches for days and offers ample legroom. However, the "30i" means a 2-liter four-cylinder turbo resides under the hood.
This would be the same engine found in American versions of the 330i and 530i, though you can't have a 730i in this market. In fact, you can't buy it in Europe either, as the base engine there is the 30d, which is a 3-liter.
BMW's turbocharged system offers you 258 HP and 400 Nm (295 lb-ft) of torque from 1,550 rpm which goes to the back wheels via the usual 8-speed automatic gearbox from ZF. The 0 to 100 km/h sprint time is claimed to be 6.3 seconds and you can still go 250 km/h despite the bulk of this car.
People who don't know how to read BMW badges might think this is a really hot sports sedan because it has been fitted with the M Sport body kit. This makes the front air intakes look almost as bold as those on the M760Li with three times the cylinders and displacement.
You'd think that a smaller engine would need less air for combustion, but BMW still installed its massive and quite controversial new kidney grille, which is about 50% larger than before. With active aero, this can at least close off to streamline the front at speed.
If you'd like to see what the 730Li looks without the M Sport package, we've got one in the luxury line added to the photo gallery below. But there's still no getting around that grille.
Other customization options on the 730Li include the Adventure Red II paint from BMW Individual and some M-themed wheels. The interior is one of the nicest we've ever seen, with a stone-like finish. I think this is Poplar Grain in grey, so it's still technically wood grain unless I'm mistaken.
