Watch 14 hot rides take over concept car lawn at Pebble Beach

The Pebble Beach Concours d'Elegance is an annual celebration of the beautiful, old cars that grace Monterey Car Week. But Monterey – and Pebble – features lots of newer metal, too, and that includes the concept lawn at Pebble Beach. Now, "concept lawn" isn't a totally accurate name anymore, and you'll see why in the list below. This year especially, plenty of production cars can be found in the area once reserved for the conceptual. Still, we're happy to see them. Here's what's featured this year: Alfa Romeo 4C Spider Audi R8 BAC Mono Bentley EXP 10 Speed 6 BMW 3.0 CSL Hommage R Buick Avenir Galpin-Fisker Rocket Speedster Hyundai HCD-16 Vision G Coupe Icona Volcano Infiniti Q60 Lamborghini Asterion LPI 910-4 Maserati Ghibli McLaren 570S Rolls-Royce Wraith By our count, that's seven concepts out of fourteen cars. But it still makes for one hot group of metal. Check 'em out in the gallery above.

Porsche announces plan to replace 911 GT3 engines

About a month back, we reported that Porsche was suspending delivery of its 911 GT3 due to reported incidents of the engine bursting into flames. A few days later, Porsche told owners of the new track-ready models not to drive their cars and had their local dealers pick up the cars in question. Just a couple of days ago, we reported that Porsche was working on a fix, and now we have the official details.
Following an internal investigation prompted by two such incidents, Porsche has confirmed that is has identified the problem as resulting "from a loosened screw joint on the connecting rod." The loose connecting rod, Porsche found, damaged the crankcase, which in turn resulted in oil leaking and then - in at least two cases - igniting.
Our source is unaware of Porsche being contacted by GT3 owners concerned about the impact of a replacement engine on their car's collectibility or resale value.

Do we finally know which hybrid hypercar is fastest?

In order to properly compare and contrast the performance characteristics of competitive automobiles, a number of variables have to be sorted out. For instance, to diminish the human component, the same driver must be used for each lap, that driver has to be capable of wringing the maximum level of performance from each vehicle, and they should all be checked and prepared to make sure they are within manufacturer specs before hitting the track. Speaking of which, the conditions at the track – and, of course, it goes without saying that the cars have to be tested at the same location, on the same day – have to be as similar as possible. Naturally, arranging all of these variables is difficult, if not impossible, and that's especially true when the contenders are the Ferrari LaFerrari, McLaren P1, and Porsche 918 Spyder. As range-topping models from well-established performance players, these three hybrid hypercars are often lumped into the same category. But which one is fastest? Well, that's been a tough nut to crack, in part because the manufacturers themselves haven't always been willing to play along when it comes time to test these machines head-to-head-to-head. And so, with all that (probably unnecessary) preamble out of the way, we present to you the video above, in which this particular vehicular pedestal is toppled. All three cars are owned by a man named Paul Bailey, they were tested on the same day at the Silverstone circuit in England, and each had British Touring Car driver Mat Jackson at the helm. We're not going to spoil the results, other than to say that all three vehicles were incredibly fast and within spitting distance of one another at the finish line, as you would expect. Intriguingly, this video is said to be part one in a three-part series, so we have more Ferrari vs. McLaren vs. Porsche action to look forward to.
