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.

2021 Mazda CX-30 2.5 Turbo starts at $31,000

In our review of the Mazda CX-30, we said that this crossover is so gifted dynamically, it was practically begging for more power. Mazda answered by adding a new turbo engine for 2021, and now we know how much the extra grunt is going to cost. Mazda has released pricing for the more potent CX-30, and the Turbo model opens at $31,000 (including the $1,100 destination charge), putting it above even the top-trim base-engine version. The turbocharged 2.5-liter engine makes 227 horsepower and 310 lb-ft of torque on regular gas, or 250 horses and 320 lb-ft with 93-octane (against 186 hp and 186 lb-ft for the standard 2.5-liter). Besides the extra output, the CX30 2.5 Turbo also comes standard with all-wheel drive, which is $1,400 extra on the regular CX-30. Other standard features of the CX-30 2.5 Turbo include adaptive cruise control with stop-and-go capability, blind-spot monitoring, rear cross-traffic alert, lane-departure warning, lane-keep assist, automatic high-beams, and a driver alertness monitor. Also, heated seats, a sunroof, leatherette upholstery, 18-inch wheels with a black finish, a gloss-black grille and door mirrors, roof rails, LED exterior lighting, keyless entry, rear A/C vents, and an 8.8-inch touchscreen with smartphone mirroring and a Wi-Fi hotspot. That features list is considerably longer than what you'll find in the $23,000 base model and puts the standard 2.5 Turbo somewhere between the regular CX-30's Select ($25,000) and Preferred ($27,400) trims. Only the $28,550 Premium has more kit. From there, the CX-30 2.5 Turbo can add the Premium Package for $33,400, which brings leather, navigation, a head-up display, a heated steering wheel, a power liftgate, adaptive front lighting, satellite radio, Bose 12-speaker premium audio, and shift paddles. At the top of the heap is the CX-30 2.5 Turbo with Premium Plus Package for $35,000. Its finery includes a 360-degree-view monitor, parking sensors, automatic braking for the rear cross-traffic alert, Traffic Jam Assist (semi-automated lane-centering at speeds under 40 mph), auto-dimming side mirrors, and Homelink. Even with the Premium Plus Package, the CX-30 2.5 Turbo is less expensive than the CX-5 with the same engine. To get the turbo engine in the larger CX-5, you're looking at $36,385 for the Grand Touring Reserve. The CX-30 2.5 Turbo also represents a savings over the similar-sized and similarly powerful BMW X2, which starts at $37,595 with front-wheel drive and $39,595 with AWD for 2021.

Mazda CX-3 crossover coming to LA

The Mazda booth at this year's Los Angeles Auto Show will showcase some new crossovers. In addition to the refreshed CX-5 that we're expecting, the Japanese automaker has announced plans to unveil its new CX-3 compact crossover.
According to Mazda, the brand's entry into the compact CUV market will feature "the full range of SKYACTIV technology and KODO - Soul of Motion design." We take that to mean lightweight chassis and body architectures along with fuel-sipping gasoline and, perhaps, diesel engines.
The CX-3 will have to take on a slew of upcoming competitors, including the Honda HR-V, Chevrolet Trax and Jeep Renegade, and reports indicate it will share a platform with the Mazda2, which is just starting production in Mexico. We don't yet know if it will be front-wheel drive only or if all-wheel drive will be optional. The CUV is also likely to share the Mazda2's engine, which isn't yet revealed for the North American market. Japan gets the 2 with either a 1.3-liter gasoline engine or a 1.5-liter diesel.
