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.

Mazda working on lithium-ion batteries to replace lead-acid starter batteries

In the quest for ever better fuel economy, car companies are looking for every single advantage possible, no matter how small. This is evident in everything from active grille shutters to the 48-volt mild-hybrid electric assist systems like that in the new Ram 1500. For Mazda, the latest target for potential efficiency gains is the lowly 12-volt starter battery. The company announced that it is partnering with two other companies, ELIIY Power and Ube Industries, to develop a lithium-ion starter battery that would be used on mainstream models in place of conventional lead-acid units. Mazda plans to have them ready for use by 2021. The advantage here would be that 12-volt lithium-ion batteries would be much smaller and lighter than the lead-acid ones they replace. And lighter cars don't need as much fuel to move around. Plus, as an added benefit, making cars lighter also often makes them faster and better handling. This is why companies such as Lotus and Porsche have offered optional lithium-ion 12-volt batteries for some lightweight sports cars. A potential downside to the use of these batteries is increased cost. Lead-acid batteries from your local parts store will run you between $100 to $150. AGM batteries could be between $200 and $300. As for lithium-ion batteries, Lotus introduced the option on the Evora 400 in 2016, and the option cost $1,690. Odds are that a company such as Mazda won't be absorbing all those costs, meaning that the cost of these future Mazdas could increase with a change from lead-acid to lithium ion. Related Video:

Mazda seeks $2.8 billion in loans to ride out pandemic

TOKYO — Mazda has sought loans totaling about 300 billion yen ($2.8 billion) from Japan's three megabanks and other lenders to ride out the coronavirus epidemic, a source with direct knowledge of the matter said on Saturday. The megabanks — Mitsubishi UFJ Financial Group, Sumitomo Mitsui Financial Group and Mizuho Financial Group — along with the Development Bank of Japan, Sumitomo Mitsui Trust Holdings and others are set to agree, with some already having extended the loans, the person said, declining to be identified because the information is not public. All three megabanks declined to comment on the loan request, which was reported by the Nikkei business daily earlier. Mazda did not immediately respond to a request for comment.    Mazda, like most other automakers, has reduced or halted production at factories around the world for the past few months as governments try to limit the spread of the new coronavirus.     Mazda's car sales and balance sheet had been weak even before the virus slammed the brakes on demand, with its interest-bearing debt of 650 billion yen far exceeding its cash and cash equivalents, according to the Nikkei.    Mazda is scheduled to announce its financial results for the year ended in March on Thursday.
