Evo pits Toyota GT86 vs. Mazda MX-5 Miata

The latest Deadly Rivals episode from Evo gets the Mazda MX-5 Miata and Toyota GT86 (our Scion FR-S) on track for a shakedown and a whole lot of drifting with Dan Prosser behind the wheel. The UK-spec coupes have slightly different power ratings than ours, but it's all close enough to be comparable. Their Miata has 158 horsepower (ours has 155), 148 pound-feet of torque, takes 7.3 seconds to run from naught to 60 62, and costs 22,695 pounds. The GT86, on the other hand, lists a 7.6-second dash to 60 62, and a base price of 25,000 pounds. The GT86 also weighs 400 pounds more than the Mazda. That's true in the States, too – curb weight for our MX-5 is 2,332 pounds, whereas the Scion FR-S comes in at 2,758 pounds. Both cars lauded for excellent shifting, but one of them has a better front end, a sweeter engine note, more controllable cornering behavior, and is faster by a tenth of a second around the test track. And Prosser doesn't mention it, but one has a lot more body roll. But it takes more than all that to make a winner, so check out the video above to see which is which.

Mazda's next-gen SkyActiv engines will drop spark plugs in favor of high compression

Homogeneous charge compression ignition, or HCCI, is the black art of internal combustion engines that aims to produce diesel-like fuel efficiency for the cost of gasoline. Although some of its competitors have developed and subsequently given up on the tech, Mazda confirmed that the next-generation of SkyActiv engines will employ HCCI technology, improving fuel economy by 30 percent and at the same time reducing exhaust emissions. According to Nikkei, a new SkyActiv family of engines is set to debut under the hood of the next-gen Mazda3 sometime in 2018 before making its way into other vehicles. In simple terms, an engine that uses HCCI burns the air/fuel mix using pressure instead of with spark plugs, just like a diesel. At 14:1, Mazda's gasoline engines already have some of the highest compression ratios out there, but a move to HCCI means cranking up the compression to 18:1. While the tech sounds relatively straightforward, using HCCI means dealing with a number of side issues. It's one of those "on paper" ideas that compounds problems when put into practice. Heat, revs, and fuel must all be carefully managed as gasoline doesn't burn the same way as diesel. Mazda is mum on details, but the automaker seems confident that the issues have been sorted. If the new engines do indeed make it to market with HCCI, Mazda will have out-engineered GM, Daimler, and Hyundai, all of which have tried and failed to develop HCCI engines in a cost-effective package. With the market moving towards electrification, it's interesting to see Mazda still focusing so heavily on traditional internal combustion gasoline engines. It's an indication of where they see the market heading for the next few years. Although the automaker has been hesitant to move forward with hybrid and electric powertrains, Nikkei also reports that Mazda will begin mass production of EVs in 2019. Related Video:

2014 Mazda CX-5 with 2.5-liter Skyactiv engine

Back in October, we compared the relative merits of two new and very good small crossovers: the 2013 Ford Escape and 2013 Mazda CX-5. The CX-5 we tested then had Mazda's 2.0-liter Skyactiv-G engine under its hood, and it managed to just edge out the EcoBoosted Ford despite being down by some 23 horsepower and 34 pound-feet of torque. Had it been available, the 2.5-liter Skyactiv engine that we recently had the opportunity to try out in the 2014 Mazda CX-5, it may have made that comparison even easier to call in the Japanese CUV's favor.
Clearly, if you're in the market for a reasonably sized crossover, the CX-5 should, at the very least, be on your test-drive list. The new engine offering will let buyers opt for a stronger powerplant, with 184 hp and 185 lb-ft on tap. On our second day in Austin's Hill Country - the first was spent quick-spinning the 2014 Mazda6 i Sport, you'll recall - we covered a couple of hundred miles and put the new CX-5 through its paces; here's what we turned up.
