Patent application suggests Mazda rotary return

A recent patent application by Mazda reveals that the Japanese automaker is still working on the rotary engine. This could in fact be the Skyactiv-R engine found in the RX-Vision concept from the 2015 Tokyo Motor Show. As with anything Wankel-related, nothing is certain until Mazda makes a production commitment. But this filing suggests that serious development is happening in Hiroshima. The 2011 Mazda RX-8 was the last rotary-powered car you could buy in America. Slow sales, poor fuel economy, and tighter emissions standards prevented Mazda from committing to a follow-up. But the fundamental principles of the rotary - compact size and light weight - perfectly fit Mazda's Skyactiv ethos. (For an explanation of how rotaries work, click here.) In this new engine the intake port sits at the bottom of the engine with the exhaust port on top instead of the other way around. That allows for lower mounting, which improves a car's center of gravity. This rotary is also turbocharged. Putting the turbo up high helps ensure it doesn't get in the way of any body or chassis crossmembers. The implication of those claims is that somebody is thinking about how to put this engine in a car. There are other benefits as well. The short path from the exhaust port to the turbo ensures minimal turbo lag. It also allows for a close-mounted catalyst on top of the enigne, which will help emissions. Another innovation in this new engine is a triangle-shaped rotor that covers part of the exhaust port. This allows for different exhaust flow characteristics. The filing claims that that two of the four orientations allow for less airflow resistance in the exhaust port. As in previous Mazda rotaries, there are two spark plugs to manage ignition timing and combustion. But unlike in the 16X concept, Mazda's last public display of such an engine, the new rotary uses port fuel injection. Keep in mind this is only a patent application. A Mazda spokesperson refused to comment on future product, but commented "As we stated at the Tokyo motor show, Mazda is doing all that it can to bring a rotary to the market." In the meantime, keep your RX-7 prayer candles lit and hope for the return of the rotary before the end of the decade. You can bide your time by reading the entire application here.

Mazda CX-5 in auto-brake accident on Japanese test drive

As we slowly march towards a world where our cars will drive for us, there will be mishaps. Systems will act up, not behave has intended or we'll simply forget to turn them on. We all remember when Volvo tested the S60's City Safety system. Now Mazda has had an issue of its own.
During a test of a Mazda CX-5's Smart City Brake Support on a dealership lot in Japan, a prospective customer and a dealership employee were injured when they hit a urethane barrier used for testing the system. According to Bloomberg, which spoke with the Saitama Prefectural Police, the impact with the barrier left the customer with an injured neck while the dealership employee suffered a fractured arm. Considering the injuries, we imagine this wasn't a small barrier.
"For any safety function, it's impossible to be 100-percent free of accidents. These technical functions aren't always the easiest to understand," IHS Automotive auto parts analyst, Hiroshi Ataka told Bloomberg.

2019 Mazda CX-3 small crossover will start at $21,365

The figures are in for the 2019 Mazda CX-3 subcompact crossover, which will start at $21,365 when it arrives in showrooms later this month. That's $280 above the outgoing model, including a $975 destination and handling fee. Fuel economy figures are also now in from the EPA. When equipped with front-wheel drive, the 2019 CX-3 gets 29 miles per gallon in the city and 34 on the highway for a combined 31 mpg. The all-wheel-drive version is rated at 27 mpg in the city, 32 on the highway and 29 combined. Which are ... exactly the same figures as the outgoing version (so much for the promised fuel economy improvements). We detailed most of what's new about the 2019 version back in March at the New York Auto Show. Mostly, they're non-cosmetic changes: The carryover 2.0-liter Skyactiv four-cylinder picks up a couple more horsepower and pound-feet of torque for 148 total horsepower and 146 pound-feet of torque, joining a six-speed automatic transmission with manual-shift and sport modes. It also gets Mazda's G-Vectoring Control driving technology, a sportier, retuned suspension and improvements to make the driving experience quieter and more refined. Mazda says it's also added an electronic parking brake, which necessitated a redesign of the center console and armrest, adding storage space, and it redesigned the front seats and added a new rear armrest with built-in cupholders. Standard features include a new direct tire-pressure monitoring system and blind-spot monitoring with rear cross-traffic alert, two USB ports, a rearview camera, hands-free Bluetooth calling and audio pairing capability, and the 7-inch Mazda Connect full-color infotainment and diagnostic display, controllable via voice command or control knob. The new Sport i-ACTIVSENSE Package of safety technologies is available for an extra $1,100. It adds features including smart city braking support with pedestrian detection, lane departure warning, radar cruise control with stop-and-go function, LED headlights and LED combination tail lights. Other trim levels include Touring, which adds 18-inch wheels and keyless entry, and the top-level Grand Touring, which starts at $26,720 and $28,120 for front- and all-wheel-drive configurations, respectively. Grand Touring includes the Sport i-ACTIVSENSE Package, plus Parchment or black full-leather seating with high-gloss pleated piping and chrome accents on the front bumper and side sills, among other features.
