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.

Why Mazda did so well and Volvo so poorly in Consumer Reports survey

The poor performances of Tesla and all three domestic automakers got the headlines in Consumer Reports magazine's latest reliability survey, but there were other results that caught our interest. Tiny Mazda notched the biggest gain among the 29 brands included in this year's list, leap-frogging nine spots to No. 3. Buick, which was in the top 10 last year, fell 11 spots to No. 19, the biggest decline of any brand. And then there's Volvo, a brand often vaunted for its quality and reliability, dropping six spots to dead last. What gives? For starters, all three brands benefited or suffered in large part due to their relatively small portfolio of vehicles. So when raves or complaints rolled in for even one particular model, as was often the case, it weighed heavily on the entire brand. That's especially true when it involves a relatively high-volume, hot-selling model such as the Buick Enclave (more on that in a moment). Mazda fared as well as it did despite the CX-3 losing Consumer Reports' influential "recommended" status due to problems with its climate system, including leaks from the condenser and refrigerant unit that triggered a service bulletin from the automaker in late 2016. Deputy auto editor Jon Linkov said that scratch didn't hurt the overall brand, since the CX-9 crossover and MX-5 Miata both jumped up to replace it on CR's list of newly recommended vehicles, thanks to several back fixes Mazda made to both models. For Buick, the redesigned Enclave SUV earned a "Much Worse Than Average" rating after owners reported problems with the new nine-speed automatic transmission it shares with the Chevrolet Traverse as well as some issues with the climate system. There were issues with rough shifting, plus complaints about the torque converter that necessitated fixes to the computer or outright replacement. "Again, similar stuff that we saw with the Traverse: both first-year vehicles, similar powertrains," LInkov said. He said all-new vehicles or redesigns typically fare poorly in CR's reliability survey due to issues that are hard to suss out before vehicles go into everyday use by consumers. The top-selling Encore and Envision fared well, Linkov said, but were outdone by the Enclave's problematic transmission components. The Enclave was Buick's second best-selling model through September at 35,227 units. Then there is Volvo, about which there is one word to sum up its woes: infotainment.

Mazda's mission for the 2017 CX-5: Smooth out the NVH

NVH: the dreaded noise, vibration, and harshness. According to current Mazda CX-5 owners, as well as those who decided against becoming owners, NVH was its biggest area of need. Traveling in the CX-5 was just too loud, so Mazda's engineers made sure that the redesigned, second-generation model would offer its occupants a more serene environment in keeping with quieter competitors. To reduce wind noise, more aerodynamic parts were strategically placed about the exterior, while extra efforts were made to reduce low-frequency noises on coarse surfaces. According to Mazda engineer Dave Coleman, the new CX-5 is nearly as quiet as its platform-mate, the 2016 CX-9. Actually, to be very accurate, all Mazdas apart from the CX-3 and 2 (aka Toyota iA) now share that platform. Another reason compact SUV buyers opted to skip the CX-5 was its comparatively firm ride. So, while the CX-5 remains "head and shoulders above the segment for handling," according to Coleman, the ride was improved. One of the primary ways of achieving that was the adoption of rigid steering mounts, which allowed for the suspension to be less stiff without a loss in handling precision.

Under the hood, every CX-5 now comes standard with the 2.5-liter Skyactiv-G four-cylinder, with output figures to be announced at a later date. The 2.0-liter, previously standard on the Sport trim, has been exiled to other markets. However, finally making its appearance on these shores is Mazda's 2.2-liter Skyactiv-D diesel engine. Although Mazda did its darndest to make it certifiable in the United States without a urea injection system, it was ultimately unable to do so without resorting to an ultra-sluggish throttle response that engineers deemed was anathema to what was expected of a Mazda. Therefore, the diesel-powered CX-5 will indeed have a DEF tank that will need to be periodically topped off to not run afoul of emissions regulations. Otherwise, the 2017 CX-5 is very much an evolution of the SUV it replaces. Customers thought its size was just right, so its passenger and cargo area remain in the same ballpark.
