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.

What a 181-horsepower 2019 Mazda MX-5 Miata means for us, and you

Last month, we reported on a VIN filing dug up by Road & Track that showed that the 2019 Mazda MX-5 Miata's 2.0-liter Skyactiv-G engine would get a power bump, from 155 to 181 net horsepower. As for how the 2019 Miata would make that extra power, we heard rumors it'd utilize a new cylinder head allowing higher revs, accounting for that extra power. Now we have what appears to be a leaked document from Mazda Canada showing exactly where that extra power comes from. According to the document posted at Miata.net (registration required to see the image), Mazda will alter camshaft lift and valve size on both the intake and exhaust side, fit freer-flowing exhaust, and smooth and enlarge the piping on the air intake side. There are also internal engine modifications: lighter pistons with lower crowns for better swirl in the combustion chamber, lighter connecting rods, and a crankshaft balanced for higher-RPM operation. All those extra revs mean extra vibration and noise, so Mazda will ditch the single-mass flywheel for a "low-inertia" dual-mass flywheel – which will attempt to find a nice balance between DMF damping action and SMF directness. Overall, it's a pretty serious engine revision with some driveline changes that will heavily affect the driving characteristics of a fantastic driver's car. Contributing Editor James Riswick and Senior Editor Alex Kierstein, both well versed in Miatas past and present, are here to analyze what this could mean for the little roadster. James Riswick: I don't know much about them lighter crank combustion rods, but I for one welcome the news of more power to the Miata. The jump from 155 to 181 seems like a very prudent Mazda-like thing to do, accomplishing that task through various aforementioned technical wizardry as opposed to slapping on a turbocharger, exclaiming "yee-hah" and calling it a day. Alex Kierstein: That's true. I'm wary of additional power, but you do make a good point that at least this is the right way to do it. Going all-motor will keep the bright responsiveness of the engine intact. But higher revs might make power delivery peakier. Frankly, I'd be ok with moving the torque and horsepower peaks up a bit in the rev range, making it a bit more work to access the engine's sweet spot. The dual-mass flywheel should also help if low-end torque suffers, so less stalling in traffic. JR: Did wonders in the 911 and 718s.

Mazda CX-5 Luggage Test | How much cargo space?

We're already seen how Mazda's largest crossover, the CX-9, does at stuffing luggage inside its cargo hold. Now it's time for the next rung down the Mazda ladder. The Mazda CX-5 has 30.9 cubic-feet of space behind its raised back seat, which on paper, is considerably less than its top competition. The Hyundai Tucson leads the way with 38.7 cubic-feet, the Honda CR-V (39.2) and Toyota RAV4 (37.5) are basically the same, and the Subaru Forester has between 33 and 35 depending on options. However, the CX-5 does have more than the Chevrolet Equinox (29.9), Jeep Compass (27.2) and Ford Escape when its sliding back seat is in its aft-most position (33.5 when all the way forward).  Basically, this compact Mazda's cargo area is midpack, which makes it a good choice for my first luggage test of the segment. Let's see how much of the luggage in my garage fits inside. As a refresher, I use two mid-size roller suitcases that would need to be checked in at the airport (26 inches long, 16 wide, 11 deep), two roll-aboard suitcases that just barely fit in the overhead (24L x 15W x 10D), and one smaller roll-aboard that fits easily (23L x 15W x 10D). I also include my wife's fancy overnight bag just to spruce things up a bit (21L x 12W x 12D).  I started by keeping the cargo cover in place to see how much fits underneath it. The answer is the four largest bags. The two smaller ones did not. OK, now let's remove the cargo cover, which is an unusual design. Rather than a roller-type cartridge that you manually pull into place or a rigid hatchback-like unit that rises up when the liftgate goes up, the CX-5 basically combines the two. The forward bit is attached to the liftgate and unspools when opened.  To detach it, you need to unfasten these plastic clamps and then remove the cartridge reel much as you would a normal cargo cover. OK, and now here's how much the CX-5 can fit with the cargo cover removed.  All of it! That above configuration is just the first thing I came up with, but there's likely additional Tetris formations to be found. Note that the tailgate does close here but the middle cases' wheels are awfully close to the window.  I'm not going to stop there, though. I went ahead and rummaged through my garage to see what it would take to fill'er up. There you go: one duffle bag and one gym bag stuffed into the spaces. You could probably fit a grocery bag right in front there, too.
