Corvette Acronyms

The Corvette did very well in SCCA endurance racing in 1985, a fact that was shared in the car’s 1986 ad campaign.

Maybe it was just the prevailing atmosphere of the Eighties, but when the Chevrolet Corvette was redesigned for 1984, it was no longer a muscle-bound sports car. Instead, it was marketed as a high-tech marvel.

1974 Pontiac GTO

1974 Pontiac GTO

Just a thought: What if the 1974 Pontiac GTO was never actually named “GTO?” What if, instead of disappointing GTO loyalists, this extensively upgraded compact Pontiac had instead been called the Ventura GT?

Cadillac V8-6-4, What Was The Cadillac V8-6-4?

Cadillac V8-6-4 (L62) engine

What was the Cadillac V8-6-4? A glib response to this question might be, “a joke,” “a mistake,” or “ a mechanic’s nightmare.” And while the Caddy-exclusive engine was inarguably fraught with glitches, a more circumspect reply might be, “a flawed technological marvel that was about a decade ahead of its time.”

What ws the Iron Duke?

Though technically a Pontiac engine, the Iron Duke found a place under the hood of dozens of non-Pontiac models.

The Chevrolet Vega was meant to be a technical and efficiency tour de force. The good-looking, lightweight little car featured a number of cutting-edge features, and was positioned to prove that the Bow-Tie Brand—and on a broader scale General Motors—was in a position to take on the low-cost and fuel-efficient imports that were starting to show up in dealerships at the beginning of the Seventies.

1985 Pontiac Firefly

Most Americans have never heard of the Firefly, but Canadian consumers might well have considered purchasing one of these subcompact Pontiacs. A 1987 “Base” is shown.

Pontiac of Canada was well known for selling gently tweaked variations of Chevy products for exclusive distribution north of the border. The 1976-1987 Pontiac Acadian for example, was actually a retrimmed Chevrolet Chevette.

2019 5.3L V-8 DFM VVT DI (L84) for Chevrolet Silverado

The L84 5.3-liter V8 will be one of two 2019 Chevrolet Silverado engines equipped with General Motors’ new Dynamic Fuel Management cylinder-deactivation system.

Even if you’re only casually interested in automotive technology, there’s a good chance you’ve heard of Cadillac’s ill-fated V8-6-4 engine, which became available for the 1981 model year.

2001 GMC Sierra C3, What Was The GMC Sierra C3

2001 GMC Sierra C3

Even if you are only a casual follower of the new-vehicle marketplace, you are likely familiar with GMC’s popular Denali trim level. Denalis are the best-equipped, most luxuriously trimmed trucks in any given GMC vehicle model line. Denali has proven to be a profit center for GMC, with the customer take rate on the pricey trim level running as high as 50 percent on the Yukon/Yukon XL large SUVs.

Cadillac HT4100I’ve never heard it suggested that the Cadillac HT4100 V8 engine was flawed because it was rushed into production, but there is evidence to indicate that that was indeed the case.

If you don’t remember the HT4100, you’re not alone. As a result of the powerplant’s flaws (more on those in a moment) Cadillac marketing folks dropped the HT moniker after a few years, leaving subsequent updated versions of the engine unbranded.

1986 Vixen 21 TD

Any good headhunter will tell you that it pays to be flexible when looking for a job. Sure, experience is good, but being willing and able to adapt to different projects almost always impresses potential employers.

Pickup Truck Diesels

In the wake of the Volkswagen emissions scandal known colloquially as Dieselgate, German automakers have almost completely discontinued offering their diesel-engine models in the United States–at least for the time being. Yet, somehow, sales of sales of diesel vehicles in the U.S. are actually up slightly. How is that possible?
