Mazda details diesel prototype at Daytona test

Diesel has without a doubt become the dominant fuel in the modern era of endurance racing. The 24 Hours of Le Mans has been won under diesel power for the past eight years running, as has every race in the FIA World Endurance Championship since its inauguration in 2012. Yet there will only be one diesel prototype entered in the top tier of the new Tudor United SportsCar Championship this year, and it belongs to Mazda.
The last Japanese manufacturer to win at Le Mans outright, Mazda has been gradually working its way back up the endurance racing ladder once again, following the example set by Audi with diesel power. Last year it campaigned a competition-spec Mazda6 Skyactiv-D in the GX class of the Grand-Am series, but rather than simply port over the existing racer into the new series, it's fielding a new prototype instead, just as it promised a couple of months ago. And now that prototype has hit the track for the first time, prompting Mazda to release its basic specs for the first time.
Tentatively referred to simply as the 2014 Mazda Prototype, the purpose-built racecar is testing this weekend in the Roar Before the 24, the official test session at Daytona that kicks off the racing season. It packs a 2.2-liter SkyActiv-D engine that's based heavily on the production version but tuned to produce 450 horsepower and 580 pound-feet of torque in race trim. Power is channeled through a six-speed sequential transmission from Xtrac, carbon brakes from AP and 18-inch racing slicks from Continental. With the Daytona-spec aero setup, it'll top out at around 186 miles per hour.

2016 Mazda MX-5 Miata 2.0L First Drive [w/video]

The 2016 Mazda MX-5 Miata is easy to comprehend. It is an enthusiast roadster in its purest form. There's no need for any sort of sales pitch. You don't have to ramp up in order to get people excited about it. Say the words "new Miata" to anyone who cares about cars, and you've immediately got their attention. And now that I have yours, I'll to cut right to the chase. It's brilliant. That's a fact I've known for a while. I drove the Japanese-spec ND Miata in Spain earlier this year, with the 130-horsepower, 1.5-liter engine that we aren't getting in the United States. The new Miata is a modern day reincarnation of the original NA that stole our hearts in 1989. It's smaller and lighter than the outgoing NC, yet boasts more interior room. It's comfortable. It looks great. And it drives like a Miata should. In other words, it's perfect. So what about this US-spec car, then? It's got more power – 155 horsepower and 148 pound-feet of torque from Mazda's 2.0-liter Skyactiv four-cylinder engine. But it's also heavier. Our car weighs 2,332 pounds, compared to the roughly 2,200 pounds of the 1.5-liter car. Yes, the ND Miata loses 12 hp compared to the outgoing NC, but it's up 8 lb-ft of torque. Plus, according to Mazda, because of the improved powerband, anytime you're under 5,700 rpm the new Skyactiv engine is stronger than the old MZR mill. It's more efficient, too. With the manual transmission, the Miata is estimated to achieve 27 miles per gallon in the city and 34 mpg highway. That a jump of six mpg in both categories compared to the old six-speed. Consider this: The Japanese-spec car uses a 130-hp engine, which I found to be perfectly adequate. The increase in power for the US-spec car mostly just balances out the extra weight, but it also improves performance on the highway. Hit the throttle in sixth gear with the 1.5 and nothing happens. Do the same with the 2.0, and there's movement. Low-end power is far more important in the US than it is in other markets, and that's why our car has the larger engine. "North America is why the two-liter car exists," engineer Dave Coleman told me. Plus, 155 hp power means you eke out the Miata's dynamics at legal speeds. 45 miles per hour in an MX-5 is a far more exhilarating experience than that same speed in any supercar. So yeah, it's not powerful. But to paraphrase Jay-Z, the MX-5 is a super car, not a supercar.

Consumer Reports no longer recommends Honda Civic

Consumer Reports annual Car Reliability Survey is out, and yes, there are some big surprises. First and foremost? The venerable publication no longer recommends the Honda Civic. In fact, aside from the walking-dead CR-Z and limited-release Clarity fuel-cell car, the Civic is the only Honda to miss out on CR's prestigious nod. At the opposite end there's a surprise as well – Toyota and Lexus remain the most reliable brands on the market, but Buick cracked the top three. That's up from seventh last year, and the first time for an American brand to stand on the Consumer Reports podium. Mazda's entire lineup earned Recommended checks as well. Consumer Reports dinged the Civic for its "infuriating" touch-screen radio, lack of driver lumbar adjustability, the limited selection of cars on dealer lots fitted with Honda's popular Sensing system, and the company's decision to offer LaneWatch instead of a full-tilt blind-spot monitoring system. Its score? A lowly 58. The Civic isn't the only surprise drop from CR's Recommended ranks. The Audi A3, Ford F-150, Subaru WRX/STI, and Volkswagen Jetta, GTI, and Passat all lost the Consumer Reports' checkmark. On the flipside, a number of popular vehicles graduated to the Recommended ranks, including the BMW X5, Chevrolet Camaro, Corvette, and Cruze, Hyundai Santa Fe, Porsche Macan, and Tesla Model S. Perhaps the biggest surprise is the hilariously recall-prone Ford Escape getting a Recommended check – considering the popularity of Ford's small crossover, this is likely a coup for the brand, as it puts the Escape on a level playing field with the Recommended Toyota RAV4, Honda CR-V, and Nissan Rogue. While Ford is probably happy to see CR promote the Escape, the list wasn't as kind for every brand. For example, of the entire Fiat Chrysler Automobiles catalog, the ancient Chrysler 300 was the only car to score a check – there wasn't a single Dodge, Fiat, Jeep, Maserati, or Ram on the list. That hurts. FCA isn't alone at the low end, either. GMC, Jaguar Land Rover, Mini, and Mitsubishi don't have a vehicle on CR's list between them, while brands like Mercedes-Benz, Volvo, Nissan, Lincoln, Infiniti, and Cadillac only have a few models each.
