ALWAYS WANTED A 6 Series but couldn’t convince your offspring to squeeze into the back? Before last night there was only one option: give the ungrateful brats up for adoption.

But now there’s the 6 Series Gran Coupe, which landed here at a glitzy event in Sentosa Cove, attended by Singapore’s glitterati (and us). It’s a 6 Series, but with four doors. A bit like a 5 Series, then.
 
Well, not really. It has 4+1 seats instead of five, and it has the nose and tail-end styling of the 6 Series. It’s 113mm longer between the axles than a regular 6 Series, and the boot goes from 460 litres to 1,265 if you fold the rear seats.
 
It’s hard to think of something comparable; although the Merc CLS is an obvious rival, that car didn’t start out as a coupe that was stretched to accommodate two extra portals. Same with the Audi A7 or Porsche Panamera.
 
Anyway, BMW’s latest and greatest can be had in two versions – fast or brown pants fast – so you know the name isn’t short for Granny Coupe.
 
The 640i (yours for $373,800 with COE) gets familiar 3.0-litre turbo power, which means 320bhp max output, and 450Nm of peak torque from just 1,300rpm. The box of cogs has eight speeds, which translates to 0 to 100km/h in 5.4 seconds.
 
Not fast enough? There’s the 4.4-litre twin-turbo V8 650i ($428,800), which leaps to 100km/h in 4.6 seconds. The Gran Coupe is the first to get the updated version of this engine, which has been tweaked for 450bhp. Peak torque is 650Nm, available from 2,000rpm. That’s very high, from very low.
 
Both models come fitted with Adaptive Drive witchcraft suspension, something called Adaptive LED headlights, head-up display and a rear view camera.
 
Four-wheel steering is one of the more tasty options, along with a (more) fancy sound system from Bang & Olufsen and cruise control with automatic stop-go for thrill-seekers.
