Junkyard Find: 1979 Mazda RX-7
First-gen RX-7 s aren’t uncommon in wrecking yards in the western part of the country, as demonstrated by this ’79, this ’80 with incredibly of-its-time custom paint, and this fairly solid ’85. In fact, I don’t bother to photograph most of the examples I see. Today’s ’79, with its brown-and-beige tape stripes, seemed worthy of inclusion in the Junkyard Find series, though.
Junkyard Find: 1980 Mazda RX-7, With Incredibly 80s Custom Paint
First-generation RX-7s aren’t uncommon Junkyard Finds, even though the youngest ones are 27 years old now. However, not many full-on early-to-mid-80s custom paint jobs show up at junkyards these days. Here’s one I found in Denver last week.
Mazda Boss Reveals More About Rotary Range Extender
The rotary engine and Mazda have had a tumultuus, on-and-off relationship that rivals an Old Hollywood marriage. Market conditions and government regulations have made mass production of the rotary a constant challenge, and the death of the Mazda RX-8 looked like the final nail in the Wankel’s coffin.
Junkyard Find: 1985 Mazda RX-7
Back when I reviewed the final Mazda RX-8, I ranted on at some length about my envy of my RX-7-driving college classmates who were the rich sons of high-ranking South Vietnamese military officers and government officials. Still, except when I was shopping for a Mazda rear end for my 20R Sprite Hell Project, I haven’t paid much attention to the many RX-7s I’ve seen in wrecking yards over the years. First-gen examples aren’t uncommon even today; here’s an ’85 I found in a Denver yard last week.
Capsule Review: 1993 Mazda RX-7
Bribery! While TTAC has a Get Behind Me Satan approach to the buffet-table and the press junket, we’re still mostly susceptible to the kryptonite lure of interesting cars.
So when Mazda called me up and asked if I’d like to sample a little of their driving heritage in a blatant PR move, I huffily told them that I could not in good conscience be complicit in helping further burnish their brand image as a manufacturer of sporting products. I reminded them that I thought the Mazda2 too slow, the Mazda3 too ugly, the Mazdaspeed3 possessed of worse torque steer than a one-legged unicyclist, the cabin of the MX-5 designed for people with short legs and prehensile elbows, and that they didn’t even build a rotary engine any more, so what was the point?
Naturally, I said all these things in my internal voice during the 3.7 nanosecond pause before, “OohyespleaseWhencanIpickitupHowaboutnow?”
Who’s ready for some yellow journalism?
Mazda: Rotary Will Live On As Hydrogen-Powered Range Extender For EVs
A report in the Nikkei claims that Mazda’s rotary engine will live on as a range extender for electric vehicles using hydrogen power for the Wankel engine.
Mazda Says "Deuces" To V6 Engines, Welcomes Rotaries Back Into The Fold
Mazda is saying “peace out” to their V6 engines. The party line is that they don’t really fit with the companies new philosophy, and the SkyACTIV portfolio. Instead, the company is drumming up a few alternatives.
New or Used: Ending 2011 With a Bang!

Wild-Ass Rumor Of The Day: Mazda Working On Rotary Engine With Freaking Lasers?
Having seen its RX-8 banned from Europe for flunking emissions tests, Mazda may be going to extreme lengths to improve the efficiency of its next-gen rotary engine (codenamed 16x) which has been in development since 2007. Autocar reports
The 16X’s capacity has been raised from 1304cc to 1600cc, and it is also physically smaller and partly built from aluminium. The changes are designed to improve two of the biggest issues with rotary engine performance: fuel economy and torque delivery.
The Mazda source said the new engine “needed a smaller hole on the wall [of the combustion chamber]” as a result of eliminating the space-hungry normal spark plug. He also admitted to Autocar that the use of laser ignition “was absolutely possible”.
Recent advances in Japan have created high-power lasers made from ceramics that measure just 9mm in diameter and 11mm in length, easily small enough to fit into a car engine.
Not only would laser ignition allow the 16x to burn leaner, it would also allow more precise control of ignition points and timing. More importantly, it would cement the Wankel rotary’s status as the least-necessary, most overly-complex and thoroughly awesome engine ever created. And they say emissions standards always make cars less interesting…
The Doyle Rotary Engine
One of the cool things about the SAE World Congress is that there’s always at least a couple of radical new engine designs. Scuderi was back with their split cycle compressed air hybrid, only this time with a turbo that lets them use a much smaller piston on the intake side, reducing friction. FEV showed an engine optimized for compressed natural gas, with turbocharging, long intake runners, and a piston designed to increase turbulence. Two exhibitors were at the SAE for the first time. Grail Engine Technologies was showing their atmospheric-valve-in-piston engine that routes the induction through the crankcase and up into the combustion chamber.
Wankel + Automatic = Ideal Truck Drivetrain?
You’d think that the zilch-o-torque characteristics of a Wankel engine wouldn’t be so great for hauling heavy loads, and you’d be right! Adding an automatic transmission to the mix, as is the case with this ’75 Mazda pickup, no doubt made for some interesting driving experiences when hauling, say, a dozen sacks of concrete mix in the back.
Mazda RX-8 To Be Discontinued In US Market
With the Mazda RX-8 being pulled from the European marke t for its rotary engine’s inability to pass the new Euro-5 emissions standard, we should have guessed that its days were numbered in the US market as well. Perhaps the fact that the model is one of our favorite enthusiast options available in the US made us hope against hope that it would soldier on a bit longer. No such luck. According to Motor Trend‘s “well placed source at Mazda’s North American Operations,” the RX-8 will be phased out “most likely after the 2011 model year.” And probably not just for the obvious fuel economy or capacity-utilization reasons either: RX-8 sales peaked at 23,690 units in 2004, and have been in steady decline ever since, moving only 2,217 units last year.
