2019 Mazda CX-5 Turbo Drivers' Notes Review | More power, more love

The second-gen Mazda CX-5 has been on sale since 2017, but the big news for this year is the addition of a new turbocharged 2.5-liter inline-four. The engine — dubbed Skyactiv-G — is shared with the Mazda6 and the Mazda CX-9 three-row crossover and makes 227 horsepower and 310 pound-feet of torque on regular gas and up to 250 hp when running premium fuel. Fuel economy for the new engine is rated at 22 mpg city, 27 mpg highway and 24 mpg combined. The engine is only available with all-wheel drive, but the extra grunt means fuel economy is down from the naturally-aspirated 2.5-liter inline-four (24 city, 30 highway and 26 combined). The new engine is wrapped in the same familiar package we've seen for the past couple of years, but is exclusive to the range-topping Grand Touring Reserve and Signature trim levels. This particular test car was a Signature, which starts at $37,935 before options. For reference, a base, front-wheel drive CX-5 Sport starts at $25,395. Standard features on the CX-5 Signature include 19-inch wheels, LED lighting, rain-sensing wipers, leather seating, heated front and rear seats, a heated steering wheel, adaptive cruise control, proximity entry and push-button start, and a Bose audio system. Options on this Soul Red ($595) model are restricted to accessory items: $70 for a cargo mat, $125 for all-weather floor mats, $400 for illuminated door sills, $125 for a rear-bumper guard and $250 for a retractable cargo cover. The final MSRP comes in just below $40,000. Our contributor Ben Hsu had high praise for the CX-5 turbo in our recent first-drive review. Now the rest of us have had a crack at it. Editor-in-Chief Greg Migliore: I love the CX-5's looks and driving dynamics. It's a sporty Mazda tailored to the crossover segment. This one, done up in Soul Red Crystal Metallic (what a name) and Signature trim with smokey 19-inch wheels, looks great. The Skyactiv-G four-cylinder with 227 hp (on 87 octane) and 310 pound-feet of torque makes for a brisk driving experience. In Sport mode, it's almost more eager than I want it to be. The main downside is the interior. The materials are just fine, and the infotainment is a little clunky to use. It takes a few more moves than I'd like to change the radio station. Also, major demerits for not being able to put a rear-facing car seat in the middle. Considering young families are a target market for this, that is not ideal.

2014 Mazda6: Winter's End Update

The Winter Without End is seemingly dead. Outside my office windows, my brown and yellow lawn is fully exposed to the increasingly powerful sunshine, the morning birdsong is louder than anything until the garbage trucks start rolling, and I'm seriously considering having the summer tires put back on my personal fleet. That last one is a little scary, as I'm a firm believer in the April Snow Jinx, but you get the idea.
The long-term Mazda6 has also long since left my driveway. Looking back on my notes from the time it was in my charge, however, I see all remarks are dominated by one highlighted section at the top: "worst winter drive of all time." I hardly need the reminder, to be honest. Here's what happened.
When the Mazda showed up at my door, we'd already fitted the thing with its new winter rubber: Bridgestone Blizzaks. Plunking down for dedicated snow tires was a near necessity this year - as it almost always is in Michigan. We didn't see much reprieve from snow-choked, iced over roads here in Ann Arbor, and the knobbier rubber proved invaluable in getting me out of my house time and again.

Mazda patent shows rotary placement in complex AWD hybrid layout

If we were playing alt-powertrain Bingo, a recent Mazda patent application filed in Japan would be one or two letters from victory. What's exciting about the patent, discovered by Japanese outlet T's Media via Motor Trend, is that while it makes a case for an internal combustion engine of any configuration, one of the drawings showing a rotary engine. The wild bit is that the whole powertrain comprises the ICE, a transaxle, two tiny in-wheel electric motors turning the front wheels, a third electric motor in the driveline, a capacitor, a lithium-ion battery, and three inverters. Motor Trend parsed the mechanics, and the way it reads, Doc Brown couldn't have done a better job. The rotary engine at the front turns the rear wheels, but not directly. Instead of a flywheel on back of the engine, the drawing shows a 25-kW electric motor and an inverter, then a driveshaft running to the transaxle. Along the axis of the transmission tunnel in a normal car, between the inverter and the transaxle, lies a 3.5-kWh battery running at 48 volts. MT writes that the electric motor can add its output to the ICE output to drive the rear wheels, or the e-motor can turn the rear axle on its own. Up front, two inverters and a double-layer capacitor join the ICE in the engine bay. The capacitor and tiny hub motors in the front wheels run at 120 volts, a higher voltage than the rest of the electrical system, so that the small in-wheel motors can generate the same torque as a larger motor running at a lower voltage. The AWD system acts on-demand. Given the signal, the capacitors discharge their energy to the wheel motors, and recover energy from braking. When the capacitors are at full charge, they send excess regen energy to the lithium-ion battery; conversely, the battery can recharge the capacitors when they're low and the front hub motors need power. The patent explains that the ICE works with the rear e-motor to drive the rear wheels at low speeds, the front motors called on to "generate an output only when a large output is required in the high vehicle speed range." The rather complicated system is focused on providing the benefits of a hybrid system and all-wheel drive, but at lower weight than one would expect. A rotary serves due to its compactness, but one of the drawings shows an engine with a V layout. Hub motors get dinged for adding unsprung weight, hence the small motors here.
