Oliver Jarvis in a Mazda takes pole in star-studded Rolex 24 at Daytona

DAYTONA BEACH, Fla. — Oliver Jarvis broke a 26-year-old record at Daytona International Speedway in putting the Mazda DPi from Team Joest on the pole for the Rolex 24 at Daytona. Jarvis went to the top of the scoring chart early in Thursday's qualifying session with a lap at 1 minute, 33.685 seconds. It broke the mark by two-tenths of a second set by P.J. Jones in 1993 in a GTP-class Toyota. The Englishman spoiled a strong run by Team Penske, which qualified second and third for the twice-round-the-clock endurance race that begins Saturday. Ricky Taylor earned the second spot in Penske's Acura ARX-05, while teammate Juan Pablo Montoya was third in his first time qualifying the sports car for the organization. Team Joest wound up first and fourth on the starting grid with Jonathan Bomarito putting its second car on the second row. Felipe Nasr had the fastest Cadillac DPi-V.R in fifth for Action Express Racing. Nasr is the reigning IMSA champion and led the way for four more Cadillacs in qualifying. Jordan Taylor was sixth for Wayne Taylor Racing, ahead of Juncos Racing's Agustin Canapino, then Tristan Vautier and Stephen Simpson for JDC-Miller Motorsports. James Allen in an Oreca 07 Gibson for DragonSpeed won the LMP2 pole. In the GT Le Mans class, Nick Tandy put a Porsche on the pole as four different manufacturers qualified in the first two rows. IMSA GTLM champion Jan Magnussen of Corvette Racing was second, Ryan Briscoe in a Ford GT for Chip Ganassi Racing was third and followed by Davide Rigon in Risi Competizione's Ferrari 488. Marcos Gomes gave Via Italia's Ferrari 488 the pole in the GT Daytona class. Related Video:

Will the new Mazda Miata be available with multiple engines?

At this point, the countdown until the launch of the all-new, fourth-generation 2016 Mazda MX-5 Miata can be measured in hours until its September 3 unveiling as easily as it can in days. With the debut of such a highly anticipated model so close, the rumors about the new sports car are starting to boil over.
We recently heard that the new Miata would likely get a 2.0-liter Skyactiv four-cylinder with a six-speed manual, plus a decent drop in weight compared to the current gen. There's even the rumored possibility of a fastback coupe version sometime in the future.
Now, Australia's GoAuto is adding another dollop of speculation into the mix with the claim that there could be "potentially more engine options," according to Mazda Australia managing director Martin Benders to the website. The more potent option would still be the 2.0-liter Skyactiv with a power bump from its current 167 hp to closer to 200 ponies. The other possible powerplant option would be a 1.5-liter, naturally aspirated four-cylinder taken from the upcoming Mazda2 replacement. This version would also ditch some of the MX-5's more premium features to cut the weight and the price slightly.

Mazda Skyactiv-X Review | The revolution begins with a squeeze-bang

The matte black Skyactiv-X prototype looks like a rough Mazda3, perhaps reconstructed after a bad wreck by an over-enthusiastic owner of a spot welder and lots of gaffers' tape. Ribbed ducts poke out of the dash sending two breaths of conditioned air to no one in particular. Even its revolutionary engine, the thing we're here to experience, is entombed in a massive, nondescript cover to mask its unseemly noises. It's a wild, strange way to meet a very unconventional vehicle that promises diesel-like fuel economy, a wide torque band, and an exotic method for burning less gas than ever before. It takes a few hours for Mazda's engineers to explain the fundamental principles of operation. For more detail, read our Skyactiv-X Spark Controlled Compression Ignition explainer, but here's a very brief overview. Skyactiv-X marries some traditional gasoline engine characteristics with a novel form of compression ignition called SPCCI. The key for Skyactiv-X is to use very high compression in the cylinder and an extremely lean fuel-air mixture. Squeezed right to the cusp of getting hot enough to blow up all on its own (which is very hard to predict), a squirt of extra gas and a spark interject to cross that compression-ignition threshold in a controlled and predictable manner. See the animation below: That takes a few essential components to get just right. One is a massive amount of computer processing power and some pressure sensors in the individual cylinders, because the ambient conditions change how and when these things happen. Skyactiv-X uses a clutched supercharger to pump in additional air when needed to nail the mixture precisely, and high-pressure injectors to get the low ratios of fuel to disperse properly in the chamber. And since it operates like a conventional gasoline engine sometimes, it uses valve timing to lower the very high compression ratio so it doesn't reach combustion ignition in that mode. In practice, the Skyactiv-X runs in compression ignition mode most of the time. In practical terms, that means it drives like a torquey gasoline Skyactiv engine. The torque curve is broad and flat — diesel-like in that respect. That also means it can get away with using a six-speed transmission and a lower final drive for better response. There's enough grunt and economy together that Mazda can let the engine spin faster — at 60 mph, it's running at roughly 1,000 more RPM than a similar gas engine, with greater efficiency.
