Mazda engineer wants new rotary to be turbocharged

Hope springs eternal for Mazda to revive the high-revving Wankel engine for a new sports car, and the company keeps feeding that thirst with hints that it could happen. To make the possibility even more tantalizing, Mazda drivetrain and powertrain assistant manager Tetsushi Marutani tells Motoring that he wants the updated mill to pack a turbocharger. "Personally, I think that a rotary with some turbo or compressor would be good," Marutani said to Motoring. "Because a rotary, in my opinion, they require more [torque at] low speed, low down torque. So if we have some small compressor or turbo it would help." Mazda hasn't sold a rotary-powered model since the RX-8 and hasn't had a turbocharged one since the third-generation RX-7. However, the recent RX-Vision concept (above) at least hinted at a possible Wankel revival, and Mazda officials confirmed that its engineers continued to develop the engine since the RX-8's demise. The RX-Vision used a next-gen rotary called the Skyactiv-R, but Mazda didn't officially confirm any details about it. Rumors suggested the engine had a two-rotor layout with a total displacement of 1.6 liters. A two-stage electric turbo and hybrid powertrain would allegedly boost the total output of around 450 horsepower. The electric assistance could also counter the Wankel's lack of torque at low revs and poor fuel economy. Those rumored specs sound fantastic, but we still take the rotary's return with a grain of salt. Mazda CEO Masamichi Kogai is adamant that it's not worth the company's limited resources to develop a niche sports coupe instead of better selling vehicles. Related Video:

Import pickup truck-killing Chicken Tax to be repealed?

After over 50 years, the so-called Chicken Tax may finally be going the way of the dodo. Two pending trade deals with countries in the Pacific Rim and Europe potentially could open the US auto market up to imported trucks, if the measures pass. Although, it still might be a while before you can own that Volkswagen Amarok or Toyota Hilux, if ever. The 25-percent import tariff that the Chicken Tax imposes on foreign trucks essentially makes the things all but impossible to sell one profitably in the US, which lends a distinct advantage to domestic pickups. Both the Trans-Pacific Partnership with 12 counties and Transatlantic Trade and Investment Partnership with the European Union would finally end the charge. According to Automotive News though, don't expect new pickups to flood the market, at least not immediately. These deals might roll back the tariff gradually over time, and in the case of Japan, it could be as long as 25 years before fully free trade. Furthermore, Thailand, a major truck builder in Asia, isn't currently part of the deal, and any new models here would still need to meet safety and emissions rules, as well. Automotive News gauged the very early intentions of several automakers with foreign-built trucks, and they weren't necessarily champing at the bit to start imports. Toyota thinks the Hilux sits between the Tundra and Tacoma, and Mazda doesn't think the BT-50 fits its image here. Also, VW doesn't necessarily want to bring the Amarok over from Hannover. There is previous precedent for companies at least considering bringing in pickup trucks after the Chicken Tax's demise, though. The Pacific free trade deal could be done as soon as this fall, while the EU one is likely further out, according to Automotive News. Given enough time, the more accessible ports could allow some new trucks to enter the market.

Jay Leno brings a rotary-powered VW Beetle to the garage

It takes something really unique or inventive to pique Jay Leno's interest. His show, Jay Leno's Garage, has featured everything from concours-worthy classics to completely custom, home-built machinery. How do you get Leno to feature one of more than 20 million Beetles on his program? Stick a turbocharged rotary engine under the hood. The Beetle's owner, Mario Markakis, swapped the car's stock flat four-cylinder for the Wankel engine from a 1990 Mazda RX-7 Series 5 Turbo. The engine's 250 horsepower are fed through a reinforced version of the Beetle's stock four-speed transmission. That's about five times the original engine's output. It works well, with the car putting down some impressive times at the drag strip. Markakis did most of the work to the Beetle in his garage. In addition to the engine swap, he's modified the car's brakes, suspension, and interior. Check out the video to hear all the details of this custom Wankel-powered Volkswagen.
