Road & Track names its 2013 Performance Car of the Year

Road & Track recently staged its first annual Performance Car of the Year test, pitting 13 new and updated performance cars against each other on track, then graduating the top six to a road test before picking a winner. Additionally, the magazine staff picked the best automobiles of the year in eight categories.
But first, let's cover the PCotY segment. Here's the list of cars brought to the comparison test: Audi R8 V10 Plus; BMW 435i; BMW M6 Competition Package; Chevrolet Corvette Stingray Z51; Ferrari F12 Berlinetta; Ford Fiesta ST; Jaguar F-Type V8 S; Jaguar XFR-S; Mercedes-Benz E63 AMG S-Model Wagon; Mercedes-Benz SLS AMG Black Series; Mini John Cooper Works GP; Nissan GT-R Track Edition; and Porsche Cayman S.
To find out the results of the comparison, head over to Road & Track's website or check the press release below, where you'll also find the magazine's top-rated vehicles in eight categories. Want more? Head over to the 2013 PCotY hub. But before you do that, take a stab at guessing the winner of PCotY (we'll give you one hint: it isn't a Porsche).

Syrena Sport returns as rebodied Nissan 370Z

We wouldn't hold it against you if you'd never heard of the FSO Syrena Sport. FSO built the long-enduring Syrena for some 17 years nonstop, and while the machines were mostly plodding family sedans, engineers at FSO did create one version with a bit more zest. The Syrena Sport was a two-door coupe that borrowed design cues from Ferrari and was powered by a two-cylinder, air-cooled boxer engine. While originally intended for production, economic woes kept the machine from ever seeing the light of day.
Now, the Syrena Sport is back, though in a slightly different configuration. Entrepreneur Rafal Czubaj has resurrected the name for a special one-off creation designed by Pavlo Burkatskyy. This time around, there is no oddball boxer under the hood, however. Czubaj chose to use the underpinnings from the Nissan 370Z, complete with its 3.7-liter V6 engine. Buyers can choose between a 330-horsepower tune or a 450-hp iteration, and with a curb weight of 2,865 pounds, the car should be plenty quick. Expect acceleration to 60 miles per hour in around 4.5 seconds and a top speed of 180 mph.

Japan plans real-world diesel emissions test after companies fail

Japan's transport ministry plans to start real-world diesel emissions tests after an experiment found four models from Toyota, Nissan, and Mitsubishi that produced more nitrogen oxide (NOx) emissions than the nation's rules allow, according to The Japan Times. Regulators there usually only perform emissions checks in the lab. The VW diesel scandal has everyone double-checking their figures. Diesel versions of the Toyota Hiace van, Land Cruiser Prado, and Nissan X-Trail produced up to 10 times more NOx than allowed. The Mitsubishi Delica D:5 was up to five times over the limit, The Wall Street Journal reports. There was no evidence of defeat devices in the vehicles. Mazda performed well in the experiment, though. The CX-5 passed with nearly the same results on the road and in the lab. The Demio, better known as the Mazda2, did nearly as well with only slighter higher figures in the real world than in the controlled setting. The experimenters theorized the reason for the excessive emissions was that cold weather caused the engines' software to shut off the exhaust gas recirculation to prevent damage, according to the WSJ. However, this behavior also increased NOx production. Toyota, Nissan, and Mitsubishi don't have to worry about punishment from the transport ministry because this check was just an experiment. Their models already passed the mandated lab tests, which was the only requirement, according to The Japan Times. As governments begin greater real-world emissions tests, the results suggests diesels aren't very clean. A recent check in France found models from Ford, Renault, and Mercedes-Benz that didn't perform up to the standards. Regulators in India conducted similar evaluations and ordered VW to recall over 300,000 vehicles. Related Video:
