"A 350 is a 350 is a 350"—NOT! And Other Misconceptions About GM V8 Engines Debunked

With GM's rightful reputation for badge engineering—slapping the brands of their different divisions on essentially lookalike bodies—it isn't at all unreasonable that many people think that the same idea applied to powertrains in the glory days of the storied GM V8 engines like the Chevrolet 350.

Plus, there is the ubiquitous cliche uttered by many gearheads—or wannabe gearheads—when talking about the hot-rodder projects they dream of: "put a 350 in it."

It's easy to have the misconception that, if you look at a Chevrolet, a Buick, and a Pontiac from the 70s, each with a 350 ci V8, you're looking at the same engine three times.

But there's a problem: it isn't true.

Here's a quick history lesson—if you want more detail, you'll find copious amounts of research fodder on the Interwebs. In a nutshell, over the decades, Pontiac, Oldsmobile, Chevrolet, and Buick each had separate and very innovative powertrain engineering and manufacturing operations. And each, at some point, arrived at the magic number of 350 cubic inches of displacement that, for its time, packed a lot of horsepower and torque into a reasonably compact footprint.

Rotary Engine May Make Comeback as Range Extender for Electric Vehicles, Hybrids

Remember the Wankel Rotary Engine that powered the Mazda RX-7?

Today, the original Mazda RX-7 power plant continues to have a devoted cult following of enthusiasts, even though it never achieved wide commercial success. That said, Mazda did continue producing rotary engine cars until 2012, the last one being the RX-8, and plans to release its next rotary engine next year, according to Fox News.

Meanwhile, LiquidPiston Inc., an  advanced internal combustion engine technology company based in Bloomfield, CT, has other plans for a new engineering approach to the rotary engine. The company envisions its Rotary "X" engine as a better alternative for range extension in electric vehicles and hybrids.

Mazda Scores Innovation Award for SKYACTIVE-X Compression-Ignition Engine

From our perspective, there are two key ways that Mazda is strongly distinguishing itself within the automotive today's automotive industry

The first is car model design aesthetics. In a world where you increasingly need to play "find the badge" to identify the manufacturer of that latest boring crossover or lookalike Sonata- or Fusion-shaped fastback sedan, Mazda takes the intractable reality of the aerodynamic and safety-driven basic shapes that the industry feels obligated to produce today and manages to produce standout designs that are stunning enough to make a car enthusiast drool.

Mazda is also pushing the edges outward on the technology and research-and-development side. To name just a few examples, Mazda has made automotive technology news recently with a partnership with Denso and Toyota for electric vehicle R&D, an effort to obsolete the lead-acid starter battery with a lithium-ion replacement, and their latest public triumph: a Gold Edison Award for the SKYACTIV-X compression-ignition engine.
