What's the difference?
Driving naked is ill-advised, and possibly illegal, but taking a spin in the Lotus Exige 350 Sport is as close as you'd ever want to get. It's not so much that you feel you've left your clothes at home, but that the car has shed its accoutrements, and indeed its very flesh, leaving you with a kind of skeletal vehicle; just bare bones and muscle.
What this punishingly hard and fiercely focused machine does to your bones and flesh is best described as extreme chiropractry - in particular the stress of ingress and egress - but fortunately it makes up for the moans, bangs and bruises by fizzing your adrenal glands in a big way.
The question is whether the fun is worth the suffering, and the $138,782.85 price tag.
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.
To say the Lotus Exige 350 Sport exists at the very pointy end of motoring is a sharp understatement. It is, in essence, a track car that you’re somehow allowed to drive on the road, which means it's hugely compromised in various ways as a vehicle for day-to-day use, yet it's not really fair to criticise it for those failings, because commuting was never its intended purpose.
While it would obviously shine in its natural environment of a race circuit, the fact is you could also enjoy it enormously between track days if you pointed it at a suitably smooth and winding bit of country blacktop.
The performance, handling, steering and stopping are all fantastic, in the right conditions, and you can see how someone might justify it to themselves as a far cheaper version of a ($327,100) Porsche 911 GT3. The difference being that a Porsche doesn't make you fold yourself up like a pocket knife every time you get in.
The Lotus, then, is a car for the extreme enthusiast, only. And possibly for nudists, too.
Past McLarens have been accused of being a bit soulless, but this one is alive. The last time I felt like this in a car was a Ferrari F12, one of the scariest but most brilliant cars I've ever driven. Except the 720S isn't scary on the road, just sheer genius.
The 720S doesn't necessarily beat the competition but it opens up new ways of doing supercar things. It's a car that looks amazing, is more than fit for purpose but has a wider range of talents than the others.
That makes it ever more compelling, both as a piece of automotive brilliance to admire, andl as something to consider when you've got half a Sydney apartment to spend on a car.
Australian roads await, but the drive through rural English country roads and villages was a great preview. All I can say is: gimme one.
