Chris Harris pits Aston GT12 vs 911 GT3 RS vs McLaren 650S

The Geneva Motor Show is never lacking in exciting performance machinery. And this year was no exception. Our eyes, like those of Chris Harris, were drawn by two hardcore, track-focused versions of existing sports cars. Both wore the name GT3, and now Harris has brought them together for a supercar shootout. And he's thrown one more in for good measure. Those natural rivals are the Aston Martin Vantage GT12 and Porsche 911 GT3 RS, the latter manufacturer having pressed the former to drop the GT3 name to which it claims exclusive domain. There's a great deal that separates them, of course: one's got a V12 up front, the other a flat-six way in the back. But what binds them together is a common approach of taking an existing model, stripping it down, and tightening everything up to make it more of a weapon than a grand tourer. What that means in the Aston's case is a rather high price tag, much higher than that of the Porsche. But scarce demand and speculation on the open market have left British customers, at least, paying as much for the GT3 RS as for the limited-edition Aston. And that takes both into proper supercar territory. So to show what else that kind of money can get you, Monkey has brought along a McLaren. Not the similarly track-focused 675LT, but the standard 650S... Spider, no less, and with worn hard rubber. So which one performs best on the road? Which clocks the fastest lap time on the track? And which gets Harris' vote? You'll have to watch the video for yourself to find out, but it's well worth the 25 minutes of your lunch break.

Everybody's doing flying cars, so why aren't we soaring over traffic already?

"Where's my flying car?" has been the meme for impending technology that never materializes since before there were memes. And the trough of disillusionment for vehicles that can take to sky continues to nosedive, despite a nonstop fascination with flying cars and a recent rash of announcements about the technology, particularly from traditional automakers. Earlier this month, Toyota applied for an eye-popping patent for a flying car that has wheels with spring-loaded pop-out helicopter rotors. The patent filing says the wheels/rotors would be electrically powered, while in on-land mode the vehicle would have differential steering like tracked vehicles such as tanks and bulldozers. At an airshow in July, Aston Martin unveiled its Volante Vision Concept, an autonomous hybrid-electric vertical takeoff and landing (VTOL) vehicle it developed with Rolls-Royce. Aston says the Volante can fly at top speeds of around 200 mph and bills it as a luxury car for the skies. Audi used the Geneva Motor Show in March to unveil a flying car concept called the Pop.Up Next it developed with Airbus and Italdesign. If the Pop.Up Next, an electric and autonomous quadcopter/city car combo, gets stuck in traffic, an app can be used to summon an Airbus-developed drone to pick up the passenger compartment pod, leaving the chassis behind. Audi said that the Pop.Up Next is a "flexible on-demand concept that could open up mobility in the third dimension to people in cities." But Audi also acknowledged that at this point it has no plans to develop it. The cash-stoked, skies-the-limit Silicon Valley tech crowd is also bullish on flying cars. The startup Kitty Hawk that's backed by Google co-founder Larry Page announced in June that it's taking pre-orders for its single-seat electric Flyer that's powered by 10 propellers and is capable of vertical takeoffs and landings. The current version can only fly up to 20 mph and 10 feet in the air and has a flight time of just 12 to 20 minutes on a full charge. The Flyer is considered a recreational vehicle, so doesn't require a pilot's license. Uber says it plans to launch its more ambitious Elevate program and UberAIR service in 2023. "Uber customers will be able to push a button and get a flight on-demand with uberAIR in Dallas, Los Angeles and a third international market," Uber Elevate promises on its website.

Aston Martin DB11 V8 loses four cylinders but none of its grace

We love the Aston Martin DB11. Few vehicles combine speed, luxury, and comfort as well as that beautiful British coupe. That said, it's not the most efficient or affordable GT in the world, but Aston Martin is planning to change that. Starting this year, the company will offer the DB11 a twin-turbocharged V8 sourced from the mad Germans at Mercedes-AMG. We've known about the engine partnership for a while now, though we assumed the first Aston Martin to use a Mercedes-AMG V8 would be the next-generation V8 Vantage. At first, sticking a V8 under the hood might seem like an odd choice, but the DB series only recently started using V12s. Historically, the car has packed powerful inline-six engines. Offering two engines will allow the company to sell a lower-cost model and presumably boost sales. That means changes are strictly mechanical in nature. The engine is the now-common 4.0-liter twin-turbocharged Mercedes-AMG V8. Output is 503 horsepower and 498 pound-feet of torque. That's down 97 horsepower and 18 pound-feet of torque from the 5.2-liter V12. In the Mercedes-AMG C63 S, the 4.0-liter V8 makes equal horsepower and 18 more pound-feet of torque. Aston Martin says that the partnership with Mercedes-AMG allows the company to tailor the engine for Aston Martins. This means a new ECU with new engine and throttle mapping. Losing four cylinders changes the character of the car a bit. The DB11 V8 is a not-insubstantial 254 pounds lighter than the V12. Since most of the weight savings comes from behind the front wheels, Aston Martin says the V8 model is more agile than the V12 model. Engineers have adjusted the suspension bushing, geometry, anti-roll bars, springs, dampers, and stability control to account for the weight savings. The DB11 V8's diet helps offset the lower power output. As such, the 4.0-second 0-62 sprint is just 0.1 seconds off the V12. Top speed is down 13 mph to a still extralegal speed of 187 mph. We don't have fuel economy ratings for the US, but expect an improvement from the V12's current rating. The V8 will be available with all of the same equipment and trims as the V12, with just a few visual changes to distinguish the two models. The V8 gets unique wheels, darker headlight surroundings, and just two vents on the hood, available in either black or titanium. The DB11 V8 goes on sale in the US later this year. At $198,995, it undercuts the V12 model by $17,500.
