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.

Why won't automakers slap on a turbo badge anymore?

Where have all the turbos gone? Not the actual pieces that go in the engine, mind you, those are everywhere these days as automakers downsize cylinder counts and boost efficiency and CO2 claims. But the turbo badges and fanfare are missing. Back when turbos were something to get excited about there was "turbo-driven," "turbonium," and "The Turbo Zone," among other silly lines. But now that basically every car is getting some sort of boost even on the lowliest trims, automakers are almost sliding in the turbos under the radar. Or if you look at some of the nomenclature, pretending they don't exist at all. The 911 Turbo badge shows where the car goes from being sane to lunatic. It's an important border. The latest automaker to hide that it has boosted the turbo presence is Porsche with the 2017 911 lineup. Even the standard Carrera models now get turbocharged flat-six engines, meaning the 911 Turbo models aren't quite as special as they once were. Porsche is in a sticky situation with this. The 911 Turbo, after all, signifies where the 911 family takes off from being a sports car and becomes the Ferrari fighter. The 911 Turbo badge shows where the car goes from being sane to lunatic. It's an important border, but now Porsche has crossed it and is trying to downplay the fact. There are a lot of exaggerations with displacement badges today, with claims the 2.0-liter turbo four in a Mercedes C Class equates to a naturally aspirated 3.0-liter six to make a C300. Volvo is pretty far up there, too, saying an XC90 T8 means V8 power, even though it's a 2.0-liter turbocharged and supercharged four with electric assist. I don't know why BMW can't just call the car a 330i Turbo, rather than inflating the numbers up to 340i. Saab tried all of this back in the '90s when it decided to turbocharge its entire lineup, from light pressure units all the way up to models actually called "Saab 9-3 HOT" (for high-output turbo). But then the brand deleted any external reference to the turbo under the hood and people wondered why they were buying a $42,000 four-cylinder convertible. And that didn't turn out well. Even though these turbo replacements often make more power than their naturally aspirated predecessors, they're very different engines. People knew something changed when they exchanged their leased 328i with a 3.0-liter six for a 328i with a 2.0-liter turbo four.

Porsche 918 Spyder gets tiny recall for rear control arms

As the recent US recall of a single Koenigsegg Agera shows, even low-production supercars aren't immune from safety campaigns. Now, there's another example that even the fastest cars can have their faults. The Porsche 918 Spyder is a pretty fantastic vehicle for its ability to mix hybrid fuel economy and incredible amounts of power, but Porsche has a problem on a few units of its halo model.
According to the recall document from the National Highway Traffic Safety Administration, Porsche needs to inspect and possibly repair five 918s in the US because the rear axle control arms may break, which could cause a loss of control while driving. In the full defect notice, Porsche says that it first noticed the problem on June 26 when the parts failed during "heavy duty durability testing (extreme race conditions)" at the Nardo test track in Italy. It transported the components back to the company's lab for inspection, and on July 18 it issued a stop-sale to inspect the suspension parts on the supercar. The automaker also contacted owners by phone to warn them not to use the car on track, until repaired.
The affected 918s will be inspected, and if the cars have the bad parts, the control arms are will be replaced. Obviously, this will be done at no cost to owners. According to a Porsche spokesperson speaking to Autoblog, in addition to the five US cars potentially affected, there were 45 worldwide. All of the cars have now been checked.
