2014 Mazda Skyactiv Prototype looks ready for Daytona

With less than two weeks before the Mazda Skyactiv Prototype makes its race debut at the 2014 Rolex 24 at Daytona, the Japanese Zoom-Zoom brand brought its diesel-powered racer to the floor of the 2014 Detroit Auto Show.
The red prototype marks Mazda's return to prototype racing, and will campaign the inaugural Tudor United SportsCar Championship using a 2.2-liter, SkyActiv-D diesel engine. With 451 horsepower on tap and 580 pound-feet of torque, the racer should stand up well against a field of gas-powered competitors.
Should the Skyactiv win Daytona, it'll be a coup for Mazda. The racer is running an engine with over 50 percent of its parts drawn from the oft-delayed production Skyactiv-D. Head up top for our full gallery of images of the new Skyactiv Prototype. The 2014 Rolex 24 will be run from January 25 to 26.

2016 Mazda MX-5 Miata first engine shot revealed

We've dug deep for just about every scrap of 2016 Mazda MX-5 Miata info available out of the car's California reveal celebration, but powertrain particulars have been especially hard to come by. While we still don't have engine specifications, the folks over at Autoweek have scored a nice scoop - the first underhood photos of one of the display cars.
In the image above, the ND-generation Miata is clearly shown to be powered by a Skyactiv inline four-cylinder, as expected, but its displacement remains unclear. The engine is most likely either the 2.0-liter Skyactiv-G engine offered in low-end Mazda3 and CX-5 models or the 2.5-liter Skyactiv-G found in those same vehicles' upper trims. In those iterations, the 2.0-liter generates 155 horsepower and 154 pound-feet of torque, while the larger-displacement engine nets out at 184 hp and 185 lb-ft. There is no sign of a turbocharger, a feature rumored to be fitted to at least one test mule. There has also been previous rumors of a 1.5-liter Skyactiv engine, possibly for overseas markets.
The 2.0-liter strikes us as the most likely scenario, particularly as Mazda has worked diligently to save every gram in the new car, dropping a pledged 100 kilograms (220 pounds) over the current model, even while adding content. It's entirely possible that the alleged turbo car was, in fact, a mule for the Miata's Alfa Romeo sister car, which is expected to have a wholly different powertrain. Or it could simply be a second engine option for an eventual Mazdaspeed variant, perhaps.

Next Mazda MX-5 Miata to weigh a ton(ne), literally

Looking at recent spy shots of the fourth-generation Mazda Miata, it's obvious this sporty little roadster will grow in size compared to the current model, but it's also going on a diet. At the Tokyo Motor Show, Auto Motor und Sport sat down with Mazda executive Kiyoshi Fujiwara, who gave a little more insight into the Miata's redesign.
Fujiwara said that they're aiming for a curb weight of a tonne (metric ton), which is 1,000 kilograms or right around 2,200 pounds, for the next-generation Miata. This would make the roadster at least 300 pounds lighter than the current NC Miata, but still about 200 pounds heavier than the original NA.
There is no indication as to how Mazda will go about removing that much weight from the bigger car, but with as popular as the power retractable hard top (PHRT) model is on the current car, the new Miata may ditch this feature to lose its weight. Improving the power-to-weight ratio appears to be a key goal of the Mazda team, so we also wouldn't be surprised to see a more powerful engine underneath the longer hood.
