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.

Confirmed: Mazda Miata gets more power, higher redline, telescoping wheel

Our friend over at Road & Track, Bozi Tatarevic, has a keen nose for stuff just like today's Miata news, and he spotted an article by the Japanese car magazine Car Watch that details Mazda's upcoming updates. Car Watch actually got to drive the car, too. There's a lot to go through, but the highlight has to be confirmation of what we told you earlier this year about a significant power bump: The Miata will indeed get an increase of 26 horsepower, from 155 to 181. But the power's not the whole story. Mazda has increased the redline from 6,800 RPM to 7,500. It's not clear at this point where torque and power peaks are in the rev range, or how these changes affect low-speed drivability, but more revs are almost always a good thing and aren't likely to detract from the roadster's fundamental goodness. Car Watch reports that lighter pistons and connecting rods are fitted to help reduce rotational mass in the 2.0-liter inline-four. Some valvetrain changes were needed to support the higher redline, mainly stiffer valvesprings to prevent valve float. Mazda also changed the shape of the valves and optimized the intake ports to breathe better at higher RPM. The inner diameter of the exhaust ports were increased to flow better through a new muffler better tuned to the engine's new operating range. This confirms and gives a little more detail to what we reported earlier based on a leaked document from Mazda Canada. Car Watch also confirms that the revised Miata will get a low-inertia dual-mass flywheel, which should help absorb some vibration, noise and harshness from the higher-revving engine without losing too much of the directness that a single-mass flywheel provides. Mazda usually gets stuff like this right, so while we won't know until we get a chance to drive it whether the DMF feels "right," we're not too worried about it. There's also a telescopic steering wheel, a first in any Miata, which has a range of about 1.1 inches. That doesn't sound like much, but it should help folks with longer legs reach the wheel without having to crank the seat forward. Interestingly, Car Watch reports that the telescoping wheel was opposed by some in the company seeking to save every fraction of an ounce of weight, and to get it through, the company apparently had to change some of the material in the upper steering column from steel to aluminum to satisfy the weight-conscious. Little details like these are fantastic.

2021 Mazda3 2.5 Turbo starts at over $30,000

Following its introduction a few weeks ago, we now have official pricing for the 2021 Mazda3 2.5 Turbo. The most affordable version is the sedan starting at $30,845. The hatchback adds $1,000 for a total of $31,845. The full list of standard features hasn't been announced, but either model comes standard with all-wheel-drive, an automatic transmission and the turbocharged 2.5-liter four-cylinder that makes 250 horsepower and 320 pound-feet of torque on premium fuel. A higher Premium Plus trim is available for the turbo Mazda3, too. It starts at $33,395 for the sedan and $34,695 for the hatchback. One of the key features added to the Premium Plus is an "Aero Kit" that adds front and rear spoilers to the hatchback, and a rear spoiler to the sedan. An enhanced version with sideskirts and a rear diffuser is also available for an additional $1,075. The complete kit is available as an option on the base turbo hatchback for $1,900. The trim also adds leather upholstery, navigation, low-speed lane-keep assist called "Traffic Jam Assist," parking sensors and rear automatic emergency braking. Furthermore, you can add 18-inch BBS forged wheels to not just the turbo 3, but any model, and a full set will cost you $3,675.80. At the other end of the spectrum is the revived Mazda3 with a naturally aspirated 2.0-liter engine. It makes just 155 horsepower and 150 pound-feet of torque and is only available on the sedan with an automatic transmission and front-wheel-drive. It starts $21,445, bringing the base price for the small Mazda down by $1,000. The base price for the naturally aspirated 2.5-liter sedan still starts at $22,445. One final note, the Mazda3 2.5 S with Premium Package remains the only way to get a manual transmission in the Mazda3. It starts at $28,795. You can see the full breakdown of pricing below.
