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.

I can’t remember the last time I saw a Mazda rotary pickup on the street, but this one— which I spotted in a Denver self-service wrecking yard a couple days ago— survived long enough to stay out of The Crusher’s way until the second decade of the 21st century.

    I love REPU's. I would love to add one to the fleet, but this on is a bit far away I think. Very cool truck, and have a huge following amongst Rotary fans. I'm amazed this one got junked. There were two at the Deal's Gap Rotary Rally last year, and were crowd favorites. One of them was still original paint/unrestored.

    I learned to drive in a '75 mazda B1600. That truck was absolutely indestructible. And, having a manual choke in hand was a great "feature". I always loved the sorta military look of the rear end.

  • SCE to AUX All that lift makes for an easy rollover of your $70k truck.
  • SCE to AUX My son cross-shopped the RAV4 and Model Y, then bought the Y. To their surprise, they hated the RAV4.
  • SCE to AUX I'm already driving the cheap EV (19 Ioniq EV).$30k MSRP in late 2018, $23k after subsidy at lease (no tax hassle)$549/year insurance$40 in electricity to drive 1000 miles/month66k miles, no range lossAffordable 16" tiresVirtually no maintenance expensesHyundai (for example) has dramatically cut prices on their EVs, so you can get a 361-mile Ioniq 6 in the high 30s right now.But ask me if I'd go to the Subaru brand if one was affordable, and the answer is no.
  • David Murilee Martin, These Toyota Vans were absolute garbage. As the labor even basic service cost 400% as much as servicing a VW Vanagon or American minivan. A skilled Toyota tech would take about 2.5 hours just to change the air cleaner. Also they also broke often, as they overheated and warped the engine and boiled the automatic transmission...
  • Marcr My wife and I mostly work from home (or use public transit), the kid is grown, and we no longer do road trips of more than 150 miles or so. Our one car mostly gets used for local errands and the occasional airport pickup. The first non-Tesla, non-Mini, non-Fiat, non-Kia/Hyundai, non-GM (I do have my biases) small fun-to-drive hatchback EV with 200+ mile range, instrument display behind the wheel where it belongs and actual knobs for oft-used functions for under $35K will get our money. What we really want is a proper 21st century equivalent of the original Honda Civic. The Volvo EX30 is close and may end up being the compromise choice.
