2019 Mazda CX-3 crossover updated with a tad more power and refinement

NEW YORK — Mazda's smallest vehicle, the CX-3 subcompact crossover, is getting a refresh for the 2019 model year. Visually, you'd be hard-pressed to tell what changed, and that's because not much did. The grille now has slats that are grouped in pairs, and the rear taillights have been redesigned. But there are a number of changes aside from visuals that separate this model from the 2018. Under the hood is still a 2.0-liter naturally aspirated four-cylinder engine. It picks up two more horsepower and pound-feet of torque for totals of 148 for each, though Mazda says that it also picks up torque across more of the rev band and gets better fuel economy. Mazda didn't have official mileage numbers, though. The CX-3 will also now come with the G-Vectoring Control system that helps improve turn-in by reducing torque and shifting weight forward. The steering and suspension have been slightly retuned, and the tires developed to better absorb bumps. Deeper inside the CX-3, several changes should make the driving experience more calm and refined. These include thicker door panels and rear door glass to make things quieter. The seats are now wider with redesigned foam cushions for greater comfort. A new integrated armrest in the center console and one in the rear seats with cup holders help the same cause. Mazda will also add faux suede trim to the cabins of CX-3s for a more premium feel. Pricing hasn't been announced for the new CX-3, but the little crossover will go on sale in late spring. So expect pricing to come soon. Fuel economy numbers will likely be available soon, too. Related Video:

Consumer Reports says infotainment systems 'growing first-year reliability plague'

The Consumer Reports Annual Auto Reliability Survey (right) is out, and the top two spots look much the same as last year's list with Lexus and Toyota in first and second place, respectively. However, there are some major shakeups for 2014, with Acura plunging eight spots from third in 2013 to 11th this year, and Mazda replaces it on the lowest step of the podium. Honda and Audi round out the top five. This year's list includes six Japanese brands in the top 10, two Europeans, one America and one Korean.
Acura isn't the only one taking a tumble, though. Infiniti is the biggest loser this year by dropping 14 spots to 20th place. Other big losses come from Mercedes-Benz with an 11-place fall to 24th, and GMC, which declines 10 positions to 19th.
Perhaps unsurprisingly, it's not traditional mechanical bugs hauling down these automaker's reliability scores. Instead, pesky problems with infotainment systems are taking a series toll on the rankings. According to Consumer Reports, complaints about "in-car electronics" were the most grumbled about element in new cars. Problem areas included things like unresponsive touchscreens, issues pairing phones and multi-use controllers that refused to work right.

Watch what happens inside a rotary engine

Since it looks like Mazda may very well revive the Wankel rotary engine as a range extender for electric cars, there's no better time to become reacquainted with the quirky internal-combustion engine. And there's hardly a better way to become reacquainted than by peering into a running rotary engine, which you can do with the video above. The video comes to us from the YouTube channel Warped Perception. The channel has already shown what happens inside a conventional internal-combustion piston engine by putting a clear cylinder head on top of a flathead engine. This new video shows off the rotary engine by adding a clear side to a tiny model-airplane engine, something that we weren't aware existed and are glad to know about now. Despite the tiny size, the engine is functionally almost exactly like the bigger versions you'll find in Mazdas from about 1967 to 2012. It has intake and exhaust ports on the edges of the rotor housing, and the triangular rotor swings about in a peanut-shaped housing. For maximum effect, jump to right around the 7:40 timestamp. This is the point at which a bit of acetylene is added to the air-fuel mix for a brighter flame. It's at this point that you can really see when the mixture combusts and how the pressure of the flame pushes the rotor to produce rotational motion. Each stage of the video does slow things down to make everything as clear as possible. Even if you already knew how rotary engines worked, it's still fascinating to watch, first because it's something you don't get to see usually, and also because of the engine's elegant simplicity.
