Nissan's Le Mans prototype V6 to power next GT-R

You can debate all you want about whether racing has any relevance to road cars. And while you're doing that, Nissan will be getting the most out of its GT-R LM Nismo. In fact, the latest reports indicate that the Japanese automaker will use the engine (or some version thereof) in the next-generation GT-R. The Nissan GT-R LM Nismo, for those who may have missed it, is the company's radical attempt to take on the Audis, Porsches and Toyotas of the top-tier LMP1 class in the FIA World Endurance Championship. And to do so at its flagship event, the 24 Hours of Le Mans. Only unlike its rivals, it's not a mid-engined, all-wheel-drive design; both the engine and the driven wheels are at the front end. That engine, however, isn't actually all that radical. It's a 3.0-liter twin-turbo V6 producing 550 horsepower. Potent, but nothing earth-shattering. In fact it's not far off from the 545-hp 3.8-liter unit in the current production GT-R. And according to Top Gear, in speaking with the racing program's director Ben Bowlby, it will be essentially the same engine that will power the next road-going GT-R. Now if you're thinking that something's missing here, you're right: the GT-R LM Nismo packs a lot more than 550 horses. It actually has over 1,250 on tap. The remaining 700 hp are kicked in by the electric component of the racing prototype's hybrid powertrain. The next GT-R is widely expected to incorporate hybrid technology as well, but it won't be good for 700 hp all on its own. And it will almost certainly be driving all four wheels like the current version. Related Video:

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.

AAA ranks Tesla Model S P85D best green car of 2015, Versa is best value

Reviewers from all parts of the automotive world just seem to love the Tesla Model S, whether it's the pragmatists at Consumer Reports or the enthusiasts at Car and Driver. You can add one more to that list because the 2015 P85D grabs the top spot in AAA's fifth annual Green Car Guide, after Tesla's win last year too. The organization's ranking of 88 green models also names the 2014 Nissan Versa SV as the best value in the segment. To take the victory, the P85D had to score the most points over 13 categories, including emissions, acceleration and cargo capacity, and it won handily with 94.87 points. There was nearly a tie for second place, though. The 2015 Volkswagen e-Golf SEL Premium scored 85.5 points, and the 2014 BMW i3 narrowly came in third with 85.4. The best value award is based on the as-tested price per point scored. So while the Versa SV only had 64.5 points overall, its low price meant that each one cost just $249. Second place went to the Versa Note SV with 64.63 points at $260 each, and third was the Hyundai Accent GLS with 61.1 points for $269 each. Keep in mind, AAA's ranking doesn't attempt to find the most environmentally friendly vehicle, rather it tests the green car segment to give recommendations to buyers. Battery electric powertrains, compressed natural gas, clean diesel, hybrids, partial zero-emissions vehicles, and simply models with high fuel economy are all counted by the organization. The results are published in a 160-page magazine, which you can read here. It also offers suggestions on economical driving and explains some of the fuel-saving tech currently available.
