BMW 6 Series vs McLaren 720S

What's the difference?

What happens when you struggle to sell an odd-bod, not-quite-a-coupe, sort-of-a-hatchback, almost-an-SUV model? Well, sometimes it gets axed, and replaced with a new model that bears a new name.

That's pretty much it in a nutshell for the BMW 6 Series Gran Turismo, which was formerly the 5 Series GT. It essentially takes the place of the 6 Series Gran Coupe - an alternative to the regular 5 Series sedan that's more attainable than a 7 Series limousine.

Confused? It's not as difficult as all that sounds - you just need to know that this model, the 2018 BMW 6 Series Gran Turismo, is supposed to offer a neat alternative to the go-to family luxury car or SUV.

I spent some time in the entry-level 630i to see if it can deliver on that promise. In fact, I spent more than 24 hours driving the BMW 6 Series GT over the past week, and I don't have a sore back, I haven't been left scratching my head over the intended purpose, I haven't been uncomfortable, and I haven't been left wanting for much.

Years ago, McLaren wasn't really making McLarens. The ill-fated SLR was still in production, but was an oddity that made little sense - it was a highly specialised Mercedes and built to sell for crazy money to mega-rich F1 fans. Production was down to a trickle,and  the iconic and legendary F1 had completed its run a decade earlier.

The "new" McLaren Automotive had a shaky start in 2011 with the unloved MP4-12C, which became the 12C and then morphed into the 650S, getting better with each reinvention. 

The P1 was the car that really grabbed the world's attention and was then-new designer Rob Melville's first project for the British sports car maker. 

Last year, McLaren sold its 10,000th car and production numbers are closing in on Lamborghini's. Sales have almost doubled in Australia and Rob Melville is still there, and is now the Design Director. The company, clearly, has done very, very well.

Now it's come time for McLaren's second generation, starting with the 720S. Replacing the 650S, it's the new Super Series McLaren (fitting in above the Sport Series 540 and 570S and below the Ultimate P1 and still-mysterious BP23), and is a car McLaren claims has no direct competitors  from its rivals at Ferrari or Lamborghini. 

It has a twin-turbo V8, a carbon fibre tub, rear-wheel drive and bristles with cleverness.
