Recharge Wrap-up: Tesla road rage video, Mazda tests EVs vs. hybrids

A Tesla Model S driver was caught driving recklessly in a dashcam video. On Toronto's Don Valley Parkway, the driver of a white Model S can bee seen speeding along the left shoulder. Another car moves partway onto the shoulder to block the driver, who moves back into the left lane. As traffic slows, the driver pulls back onto the shoulder and speeds away. The folks at Teslarati suggest that this serves as an example of why vehicle autonomy could make the roadways safer. See the video above, and read more at Teslarati. Formula E will be broadcast live on Italy's Rai network for the next two seasons. The programming will include the live races, as well as practice and qualifying highlights, podium celebrations, interviews and other pre- and post-race coverage. "It's a great opportunity for Formula E and motorsport fans to have Rai broadcasting the live races of our series in Italy," says Trulli Formula E team owner Jarno Trulli. "It's a step forward to make the series grow and get stronger after a successful first season. I'm looking forward to cooperate with Rai and show the Italian fans what we are truly doing with our technology." Read more from Formula E. A new study links a decline in cancer risk to California's air quality regulations. The study from CARB found that cancer risk from toxic air contaminants declined 76 percent from 1990 to 2012, a time period that corresponds with regulations targeting those contaminants. Even as the amount of diesel miles driven has steadily increased, cancer risk from diesel particulate matter has declined significantly. The paper predicts that cancer risk will continue to drop as a result of controls on toxic emissions. Read more at Green Car Congress. Mazda is conducting consumer trials of hybrid and electric vehicles in Japan to gauge reception. Depending on whether hybrids or EVs prove to be more popular, Mazda will adopt one of the two types of powertrain for future production vehicles. The automaker is currently testing an electric Mazda2 against a hybrid Mazda3. While this round of testing is focused on the automaker's home market, Mazda may need to expand trials to the US in response to tightening regulations in California. Read more at Green Car Reports.

Mazda patents show rotary engine for range-extended EV

Two years ago, Mazda introduced a fascinating range-extended electric car called the Mazda2 RE Range-Extender. It took an electric Mazda2, and dropped in an itty-bitty 330cc rotary engine. It wasn't the rotary-powered sports car we had hoped for, but it seemed like a unique way to keep the quirky engine alive and kicking. But not long after the car's reveal, it seemed to disappear. Now the basic idea has resurfaced with a few modern updates in a couple of US patents. The first patent is pretty straightforward and describes a range-extended EV similar to the BMW i3. At the front is an electric motor driving the front wheels. At the back is an internal combustion engine that powers an electric generator. In the middle is a lithium-ion battery for storing and delivering electricity. It's the same set-up as that Mazda2. The second patent is for an engine start-and-stop system, but specifically for rotary engines. The system is designed to shut off a rotary engine when not needed, much as modern piston engines do. It also stops the rotor in a position that closes the intake port to ensure no fuel or exhaust emissions slip out through the intake tract. This is necessary since there are no valves in a rotary, and air and exhaust come through ports that are "opened" and "closed" by the rotor itself. The patent also describes the possibility of firing a spark plug after the fuel has been cut to eliminate any leftover fuel emissions. This system would theoretically improve a rotary engine's fuel economy and emissions significantly, which would be a boon as those are two of the rotary's major weaknesses. The rotary-engine patent also includes the same range-extended powertrain drawing as the first patent. It's there as a description of a possible application. And in such an application, where the rotary wouldn't have to run all the time, the system could take advantage of the rotary's inherent strengths. Weight can be kept low thanks to the engine's small dimensions, which should help in keeping the car sprightly and efficient. Rotaries are renowned for smoothness, too, so it shouldn't need too much refining and sound deadening, the latter of which adds more weight. The small size would also help with packaging, leaving more space for people, cargo, or possibly batteries. And since it has been patented, the company may be looking to bring the system to market.

Mazda CX-30 'just right' crossover will head from Geneva into production

As more and more customers move into the crossover segment, the less the segment is one-size-fits-all, or even three-sizes-fit-all. As such, Mazda has taken the opportunity at the Geneva Motor Show to offer a new, "just right" crossover to its lineup. The 2019 Mazda CX-30, as it's called, slots between the diminutive CX-3 and the compact CX-5 crossovers. The CX-30 shares the "Kodo" (meaning "soul of motion") design language Mazda does so well, and the execution here is excellent, too. We love the long hood and simple but elegant curves, the way the light reflects off the sides in dramatic waves. Its no surprise that Mazda chose its Soul Red Crystal to show off the new model. Mazda says it had four goals for the CX-30, two of which had to do with the size of the vehicle. It needed to be small enough to be highly maneuverable, so that drivers wouldn't hesitate to take it anywhere they need to go, but it also had to be roomy enough to provide a comfortable space for multiple passengers to easily enjoy one another's company. Mazda wanted the design to "embody the joy of owning something that matches your sensibilities." Finally, it had to perform in a way to provide peace of mind and a relaxing driving experience. Mazda will offer the CX-30 with its Skyactiv-G 2.0 gasoline engine with cylinder deactivation, Skyactiv-D 1.8 diesel engine and its new Skyactiv-X engine with gasoline compression ignition. Both gasoline engines will use Mazda's mild hybrid technology to help improve fuel economy without sacrificing performance. The CX-30 will also be offered with Mazda's I-Activ all-wheel drive and G-Vectoring Control Plus for maximum grip and stability. It will be available with either a six-speed manual or six-speed automatic transmission. The CX-30 is equipped with a driver monitoring system to improve safety using an infrared LED and camera to watch the driver's face for signs of drowsiness or inattentiveness. It'll alert the driver to pay attention, and will sound the braking alert earlier. Other active safety systems include available Front Cross Traffic Alert and Cruising & Traffic Support, the latter of which will employ accelerator, brake pedal and steering operations in traffic jams to help avert driver fatigue. Mazda hasn't said whether it will offer the CX-30 outside of the European market. Related Video:
