2019 Mazda CX-5 Signature AWD diesel unveiled in New York

NEW YORK —It seems like we've been waiting forever, but the wait is finally over. Mazda has finally launched a diesel version of the CX-5 for the U.S. market, unveiled at the 2019 New York International Auto Show. Specifically, the 2.2-liter Skyactiv-D turbo-diesel engine will be offered in the higher-end CX-5 Signature AWD, part of what Mazda calls its "path to premium," as the company continues to set its sights on some of the more expensive competition. The Skyactiv-D 2.2 makes use of a sequential twin turbocharger that employs a smaller turbocharger first at low rpm for quick throttle response, after which a valve opens to spool up a larger turbocharger at higher rpm. Mazda says this provides "smooth and linear response from low to high engine speeds, and greatly increases low- and high-end torque." Mazda estimates the output of the engine to be 168 horsepower at 4,000 rpm and 290 pound-feet of torque from a low 2,000 rpm. The engine has a rev limit of 5,500 rpm. As of right now, it's only in the all-wheel-drive version and only in the Signature trim level. As such, it gets a ho-hum EPA fuel economy rating of 27 mpg city, 30 highway and 28 combined. We previously saw fuel economy figures for a potential front-drive diesel CX-5 getting just slightly better fuel economy, at 28 city, 31 highway and 29 combined, but no word yet on if and when that'll be made available. The mediocre diesel fuel economy, while expected given the midstream shift from one emissions strategy to another, is particularly disappointing in context. The non-turbo CX-5 AWD, which makes 187 hp and 186 lb-ft, gets 24 city and 30 highway for 26 combined mpg – just 3 mpg less in the city and 2 mpg less overall than the diesel. The much more powerful CX-5 Turbo, which makes 250 hp and 310 lb-ft, gets 22 city, 27 highway, and 24 combined. Mazda is taking pre-orders for the 2019 CX-5 Signature AWD with Skyactiv-D 2.2 starting now, at an MSRP of $42,045, including $1,045 in destination fees. We have to point out that this is a sizable jump in MSRP from a CX-5 Signature AWD with the more powerful turbo engine, which lists for $38,235 – a $3,810 difference in fact. Given the lackluster fuel economy and considerable decrease in power and torque, we're concerned that the diesel may be a tough sell at this sort of premium.

Here's what you had to say about the Tokyo Motor Show

We obsessively covered the 2017 Tokyo Motor Show. You, our readers, provided the color commentary. Read on and, of course, leave your comments below. Subaru Viziv Performance Concept: Remember the WRX concept they showed in 2013, and what the production version looked like in 2015? Pepperidge Farm remembers. wooootles 2 foot high wing on the trunk or gtfo :) sc0rch3d Mazda Kai Concept : Dear Honda, this is how you dynamically style a hatchback. Thank you. Dfelix70 Kudos to KODO design. There are so many things I love about this "Kai" car: the awesome split panoramic sunroof, the Jaguar-esque tails (sporting an "eyebrow up"... ala The Rock), a sleek family resemblance to the already beautiful CX-5 and CX-9. Seems suspiciously close to being a production ready Mazda3 — save for a few fanciful bits (door handles, mirrors etc). If it doesn't get too watered down by the time it hits the streets ... take my money! Randy Ross Mitsubishi e-Evolution Concept: As an 06 IX and 12 X owner, this is so upsetting. I will never buy this or care to give it another look. Hope you are glad you killed my favorite track-ready car to produce this electric junk. AcidTonic Picture the GT-R going away for a few years and coming back as an SUV. This is ridiculous. Surely someone in marketing could've came up with another cool name. Evo The Evo sedan is dead, whether this exists or not. I don't mind. Lada1200 Honda Sports EV Concept : I sure would like to see this "less is more" design aesthetic spread to their gas-powered production line. RustyShackleford Love it. I see glimpses of late 1970 Scirocco with Honda flair. Gintonics I just want ONE question answered in the affirmative, and that is... "RWD?" Henadenk AND A FEW FROM FACEBOOK: Toyota's press conference: Wake me up when they talk about the Supra. David Levinson Yamaha Cross Hub Concept: All I can think is modern day Brat, which has its own kind of charm. I'm assuming that it's a unibody design, but it seems happy to be its own thing rather than that crossover pretending to be a pickup called the Ridgeline. Would definitely take the Yamaha over the Honda, although I doubt it'll come to the states. Cole Henry Mazda Vision Coupe Concept: Face: KIA K7, Tail: Aston martin. Harold Shin A bit British, no?

Tougher than steel: Wood pulp could make lighter auto parts

KYOTO, Japan — The global push among carmakers to make ever lighter vehicles is leading some auto suppliers in Japan to turn to what seems like an unlikely steel substitute — wood pulp. Japanese researchers and auto component makers say a material made from wood pulp weighs just one-fifth of steel and can be five times stronger. The material - cellulose nanofibers — could become a viable alternative to steel in the decades ahead, they say, although it faces competition from carbon-based materials, and remains a long way from being commercially viable.> Related: Jay Leno drives the Renew cannabis car — hemp you can't dent Reducing the weight of a vehicle will be critical as manufacturers move to bring electric cars into the mainstream. Batteries are an expensive but vital component, so a reduction in car weight will mean fewer batteries will be needed to power the vehicle, saving on costs. "Lightweighting is a constant issue for us," said Masanori Matsushiro, a project manager overseeing body design at Toyota. "But we also have to resolve the issue of high manufacturing costs before we see an increased use of new, lighter-weight materials in mass-volume cars."A NEW PROCESS Researchers at Kyoto University and major parts suppliers such as Denso Corp, Toyota's biggest supplier, and DaikyoNishikawa Corp, are working with plastics incorporated with cellulose nanofibers — made by breaking down wood pulp fibers into several hundredths of a micron (one thousandth of a millimeter). Cellulose nanofibers have been used in a variety of products ranging from ink to transparent displays, but their potential use in cars has been enabled by the "Kyoto Process," under which chemically treated wood fibers are kneaded into plastics while simultaneously being broken down into nanofibers, slashing the cost of production to roughly one-fifth that of other processes. "This is the lowest-cost, highest-performance application for cellulose nanofibers, and that's why we're focusing on its use in auto and aircraft parts," Kyoto University Professor Hiroaki Yano, who is leading the research, told Reuters in an interview. The university, along with auto parts suppliers, are currently developing a prototype car using cellulose nanofiber-based parts to be completed in 2020.
