Mazda6 Skyactiv-D Racecar ready to bring diesel to Grand-Am

It may not be quite as radical as some of the company's past rotary racers, but the new Mazda6 Skyactiv-D racecar does have a notable powertrain underhood: the automaker's brand-new clean diesel four-cylinder engine.
Three of these new diesel-powered Mazda6 racers will take to the track in the Grand-Am GX class of the upcoming 2013 Rolex 24 at Daytona on January 26, with five drivers on each team. The car you see above, number 70, is sponsored by Mazda's longtime motorsports partner, SpeedSource.

Recharge Wrap-up: Mazda, Subaru and Toyota PHEV, Nomadic Power grant

The next generation of the Toyota Prius Plug-in Hybrid looks to be important for Mazda and Subaru as well. Toyota will likely need to sell more of the new plug-in hybrid to meet stricter ZEV standards in California. That means it will get more extra electric range, as customers have been asking for. Subaru and Mazda will also have to adhere to the California standards beginning in 2018. Those two smaller automakers will likely license a plug-in hybrid powertrain from Toyota in order to fulfill compliance. Read more at Green Car Reports. Tesla is partnering with Dalhousie University to improve battery technology. Tesla signed a five-year research agreement with Dalhousie's Jeff Dahn, a lithium-ion battery researcher. Dahn and the 25 researchers in his lab will work with Tesla's Director of Battery Technology, Kurt Kelty, to increase capacity through improved materials. The collaboration could be important both for Tesla's automotive and stationary batteries. "Our research group's goal is to increase the energy density and lifetime of Li-ion batteries, so we can drive down costs in automotive and grid energy storage applications," says Dahn.

Nomadic Power's mobile batteries, called Nomads, have incorporated photovoltaic systems and can be used to extend the electric driving range of a plug-in vehicle, or to provide backup power to a home. The Nomads use an intelligent energy management system to learn and predict user behavior and manage the solar system based on weather forecasts. "We see a strong future in electric-powered mobility and an increasing use of renewable energy, photovoltaic power in particular," says Nomadic Power CEO Dr. Manfred Baumgaertner. "Our mobile batteries have great potential in these markets that recently got a significant shot in the arm by Tesla's announcements." Read more from Nomadic Power, and at Green Car Congress.

8 cars we're most looking forward to driving in 2015

Now that 2014 is officially in the books, it's time to look ahead. And following our list of the cars we liked best last year, we're now setting our sights at the hot new metal that's coming our way in 2015. Some of these, we've already seen. And some are still set to debut during the 2015 auto show season. But these are the machines that keep us going – the things on the horizon that we're particularly stoked to drive, and drive hard. Jeep Renegade Not the Chevrolet Corvette Z06. Not the Ford Mustang GT350. Not the new John Cooper Works Mini. Nope, I'm looking forward to the adorable, trail-rated Jeep Renegade. And that's because I really, really, really like our long-term Jeep Cherokee Trailhawk. I do not, however, care too much for the Cherokee's looks, and I really don't like its $38,059 price tag. The Renegade Trailhawk, meanwhile, promises much of the same rough-and-tumble character as its big brother, but at what we expect will be a more reasonable price (I'm personally wagering on the baby Jeep's off-road model starting at no more than $23,000). With a 2.4-liter four-cylinder and a nine-speed automatic, it should also be a bit easier to fill than the V6-powered Cherokee. Also, I can't help but love the way the Renegade looks. It's like someone took a Wrangler, squished it by 50 percent and then handed it off to George Clinton for a healthy dose of funk. The interior, with its bright, expressive trims and color schemes should also be a really nice place to spend some time. I'll be attending the Renegade's launch later this month, so I'll have a much shorter wait than my colleagues. Here's hoping the baby Jeep lives up to my expectations. – Brandon Turkus Associate Editor Mazda MX-5 Miata Here's an uncomfortable truth: I'd rather spend a day driving a properly sorted Mazda MX-5 Miata of any generation on a winding road than I would nearly any other vehicle, regardless of power, price or prestige. It's not just that I prize top-down driving and enjoy the Miata's small size because it gives me more road to play with. I just find there's more motoring joy to be had with high-fidelity handling and an uncorrupted car-to-driver communication loop than I do with face-distorting power or grip – let alone valet-stand gravitas. But perhaps most of all, I love Miatas because they can deliver that level of feedback and driver reward at modest speeds that won't put the locals on edge or endanger lives – you can use more of the car more of the time.
