On October 21st of this year, there’s a very good chance you’ll see a swarm of hover boards, rejuvenation clinics, and of course, flying cars, littered throughout your neighborhood. Or at least that’s what fans of the classic 1989 sci-fi comedy Back to the Future Part II would have us believe.

From this video, it looks like McLaren’s->ke284 Formula 1->ke190 drivers, Jenson Button->ke903 and Fernando Alonso are ready and waiting. Featuring some of the best acting seen this side of a press conference, the dynamic duo must decide where to pilot their 650S->ke4801 time machine: either go back to 1988 and relive Ayrton Senna’s->ke4309 epic drive from the back of the grid to second (and possibly prevent his subsequent disqualification), or jump ahead to the Australian GP this coming March.

It’s an interesting question: do you go back, or leap forward? Personally, I’d probably choose visiting the future. I have so many questions: will autonomous vehicles rebel and attempt to enslave the human race? Will Elon Musk go full-bore supervillian mode, retreating to some Moon-based lair to make outrageous demands of the world’s leadership? Will every Audi->ke14 still look exactly the same? Will MINI’s->ke57 smallest model outweigh an ocean liner?

McLaren 650S

If you’re going to make a time machine, you might as well start with something nice. I’m not talking about “ooh, gull wings” nice, I’m talking about over-a-quarter-million-dollars of carbon fiber and race-bred technology nice.

The McLaren 650S supersedes its 12C->ke3514 predecessor with a variety of upgrades and enhancements. While just as slippery as the 12C, the 650S is capable of producing 24 percent more downforce at 150 mph. It’s also more powerful, with the same M838T, turbocharged, 3.8-liter V-8, but with 50 additional horses thrown into the mix, yielding a grand total of 640 horsepower. Torque is a solid 500 pound-feet.

Routing through a seven-speed, dual-clutch automatic transmission, this rear/mid-engine, rear-drive drop-top can sprint from naught to 100 kph (62 mph) in just three seconds flat, 200 kph (124 mph) in 8.4 seconds, and 300 kph (186 mph) in 25.4 seconds. Top speed is 207 mph, which should be more than enough to activate the flux capacitor.

If it turns out you do need to dodge killer autonomous vehicles, the sub-3,000 pound curb weight and exclusive Pirelli P-Zero Corsa tires mounted on 19-inch and 20-inch lightweight alloy wheels should help enormously. Slowing your leaps between eras are carbon-ceramic discs measuring 15.5 inches in the front and 15 inches in the rear.

The only problem is finding space to mount all the tubing…
