Pebble Beach Concept Car Lawn adds class to the grass

While Pebble Beach is traditionally thought of as the refuge of the pristine and pricey vintage vehicles of the world, there's no shortage of newer vehicles on display. And when we say "new," we mean really new. As in, not even in production new. This is the concept car lawn, and it's home to an eclectic group of vehicles from past and present.
Of course, calling it the "concept car lawn" is a bit of a misnomer this year (as it has been in previous years, too). Production models like the Alfa Romeo 4C were on display, alongside known quantities like the Hennessy Venom GT and modified versions of already-on-sale models, like the Rolls-Royce Phantom Drophead Waterspeed Collection.
There were a few concepts on display, though. Toyota debuted the critically acclaimed FT-1 Concept in a new shade, while BMW's Beijing Motor Show stunner, the Vision Future Luxury, was also parked on the expensive grass. Also appearing were the Nissan GT-R in sheep's clothing, the Infiniti Q50 Eau Rouge, and the recently debuted McLaren P1 GTR.

In hindsight, Musk wouldn't use Lotus for Tesla Roadster

The world will be a different place after Elon Musk builds a time traveling device (don't ask us how we know that will happen). For one thing, the Tesla Roadster of the rewritten future will not have been built using the chassis of the Lotus Elise. Also, verb tenses will be becoming even more confusing and, possibly, awkward. "We ended up changing most of the damn car" – Elon Musk We know about the not-using-the-Lotus thing because the Tesla Motors CEO said as much yesterday at the World Energy Innovation Forum at the Tesla Factory in Fremont. The two-day event, which also offers Model S test rides and a factory tour for attendees, featured a fireside chat with the electric automaker's CEO and Ira Ehrenpreis. During the discussion, Musk revealed that if he had to do it over again, he would have built the Roadster from the ground up instead of using the Lotus Elise chassis. "We ended up changing most of the damn car, so we thought later, why did we do that," he said. Another problem with the original idea for the car was the drivetrain. At first, Tesla had meant to use the motor and other propulsive bits from AC Propulsion, only to find that powertrain didn't work well in a commercial application. Instead Tesla only licensed the reductive charging patent, which allowed some integration of the inverter and charger. Besides knocking Tesla's own early efforts, the outspoken entrepreneur took a couple swings at other technologies with quotable quotes such as: "The internal combustion engine is a ridiculous thing!" and "Current lithium ion technology is better than theoretical fuel cell limits. So, game over. Why bother with fuel cells?" Looks like there are some things Musk is not interested in going back in time and changing.

Tesla Model S finally has its date with a dyno

The performance abilities - and even the burnout potential - of the Tesla Model S has already been well documented, but, surprisingly, we haven't yet seen the all-electric luxury hatchback strapped to a dyno. Fortunately, the crew over at Dragtimes has posted a video that finally gave us some real-world numbers for the family- and environmentally friendly Tesla.
As the article points out, the results might be off a little (on the low side) due to the run not starting from a dead stop, but the numbers are impressive nonetheless. Immediately upon throttle application, the dyno records almost 300 horsepower at zero miles per hour, and power peaks at 368 hp at around 55 mph (we imagine the "386HP" quoted on the video title is a typo) before trailing off to around 220 hp closer to the car's limited 130-mph top speed. This compares quite favorably to the power numbers provided by Tesla putting max output at 416 hp; the dyno provided no torque figures for the car. Dragtimes also believes this number bodes well for the car on the track, too, quoting a quarter-mile time of 12.2 seconds at 112 mph.
The video of the quiet, zero-emission dyno session is posted below, so check it out.
