What's the difference?
Obviously the headline item of the new McLaren Artura Spider is the ability to drop the top and feel the wind in your hair, or, should you live in Melbourne, at least the damp mist on your face.
But this new plug-in powerhouse has plenty more to offer than just its folding hardtop.
The coupe and convertible are more powerful, there’s a new and louder exhaust, faster gear shifts, a richer rev range, better suspension and better braking.
Oh, and there's a new feature designed to unlock your inner hooligan, but we’ll come back to that one in just a moment...
But at its core, the Artura Spider is a plug-in hybrid monster that goes someway to previewing the future of the supercar species.
Does electrification enhance the excitement? We strapped in to find out.
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.
McLaren’s most liveable offering proves hybrid heroes have a place in the supercar stable of tomorrow. Angry and affable in near-equal measure, it is utterly docile during the week and completely bonkers on the weekend.

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.
