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.

Buy a Fiat 124 Spider Abarth, get a free day of driving school

We know the Mazda MX-5 Miata and the Fiat 124 Spider are basically the same car underneath. As we pointed out in our first drive of the 124 Spider, the two cater to different drivers, so it can be tough to choose a favorite. FCA has made deciding between the two sports cars a little harder, as it will offer Abarth owners a free day of high-performance driving instruction with their cars. Anyone buying or leasing a new Fiat 124 Spider Abarth or a Fiat 500 Abarth will get a free, one-day class at the Bob Bondurant School of High Performance Driving in Phoenix. Bundling driving school with brand-new performance cars isn't unheard of – Dodge and Bondurant recently announced a similar program for the Viper – but it is quite rare for vehicles priced below $30,000. The free session will include instructor-led skid, autocross, slalom, and team rally cross activities, in addition to hot laps. While the one-day course is included for free, travel, food, and hotel expenses aren't covered. Fiat-less people can also join in on the fun buy purchasing the Abarth experience separately. Bondurant one-day classes cost at least a grand, which makes the Fiat price of $0 a good deal as long as you can get yourself there relatively cheaply. But is this enough for drivers to choose the 124 Spider Abarth over an MX-5 Club? This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

Mazda recalls Takata airbags in B-Series

The Basics: Mazda will recall 19,000 examples of the 2004–2006 B-Series pickup. The Problem: The pickups contain Takata-sourced driver's side airbag inflators that could rupture in a crash. The spray of metal shrapnel could injure or even kill occupants. Injuries/Deaths: None reported in the Mazda pickups. However, a rupturing airbag inflator killed the driver in a Ford Ranger, which is identical to the B-Series. The Fix: Mazda will replace the driver's side inflator. If You Own One: Mazda plans to notify affected owners as soon as dealers have the replacement parts. More Information: Mazda already recalled 442,266 driver's side Takata inflators and 416,475 of them on the passenger's side. The affected models included the 2003-2008 Mazda6, 2004-2006 B-Series, 2006-2007 Mazdaspeed6, 2004-2008 RX-8, and some examples of the 2004 MPV. Ford also issued an expanded safety campaign for 391,394 examples of the 2004-2006 Ranger.
