Nissan-Renault mule teases mysterious subcompact

There's always something intriguing about a mystery, especially of the automotive kind, and that's exactly what we have here. Our spies recently spotted this Nissan-Renault test mule on the road in Southern Europe. But what, exactly, are they testing? From the front end, it's clear this mule started life as a Nissan Versa Note, but check it out in profile to see the cut down rear doors. They're significantly shorter than on the production car, and the wheelbase isn't as long here, either. The tacked on fender flares suggest a wider track than stock, too. Making things even more complicated is the bizarre cladding this subcompact hatch is wearing. The odd tumors on the hood and blistered side panels indicate that the automaker is trying to keep the design underneath a secret. Given Renault and Nissan's tight relationship, it also isn't clear which company is testing this model. While the body comes from the Note, this one is wearing French license plates. According to our spies, the vehicle was also spotted leaving a Renault testing location. There are some possibilities, though. Renault already has the new Twingo out, and the next-gen Megane has an imminent release. The French brand could now be at work on a future Clio. Alternatively, Nissan is reportedly using the Sway concept as inspiration for the upcoming Micra, and we could be getting a preview here. Give us your best guess in Comments. Related Video:

This tiny 1.5L engine from Nissan makes 400 horsepower

Back in 2012, Ford packed its tiny 1.0-liter EcoBoost three-cylinder in a carry-on suitcase, destined for use in the Fiesta here in the US. In June, Nissan will pack its tiny new three-cylinder engine in a 24 Hours of Le Mans racecar. Nissan's don't-call-me-DeltaWing ZEOD RC racecar will still be able to tackle a single lap under full electric power, but the rest of the time it will be powered by the new 1.5-liter turbocharged three-cylinder engine.
Holding the lightweight engine (at right) is Nismo president Shoichi Miyatani, and he's likely smiling because that 40-kilogram (88-pound) engine packs quite a punch with 400 horsepower and 280 pound-feet of torque. Nissan would like to take a moment to point out this engine's power-to-weight is better than the engines currently used in Formula One racecars. Scroll down for more information on this new race engine, which we'll see in action at Le Mans in June.

Nissan gives us the business on the art of clay modeling

The team from The Dashboard recently stopped by the Nissan Technical Center in Japan for a look at what exactly goes into creating a full-scale clay model. While automakers have been using clay bucks for decades, designers and engineers are now combining computer renderings and hand-sculpted clay models to determine how a new vehicle will look in our world. Engineers use specially formulated clay kept warm in an oven to bring the body panels to life. They then coat the clay in a thin plastic film to add body color for the final look.
By the time everything is said and done, workers may have hundreds of hours in the model's creation. So, what happens when the company no longer needs the buck? They get scrapped. Someone comes in and dismantles the whole creation. We presume that action is set to the wailing tears of everyone who had a hand in building the model. Check out the video below for a closer look.
