Beep Beep: The Irreverent Plymouth Road Runner

Performance car enthusiasts tend to be a somewhat humorless bunch, whether you’re talking about Ferraristes, old-school muscle car fans, or import tuners. If they have one thing in common, it’s that they’re none too keen at being laughed at. That’s why it’s remarkable that one of the premier icons of the muscle car era is one of the most irreverent of them all: a budget Supercar named after a cartoon bird — the Plymouth Road Runner. This is its story.

Living in interesting times

Owing to the intrusion of other projects, this week’s regular article is going to be delayed until next week. So as not to leave you too wanting for content, though, I thought I would discuss a little more about the philosophy of this site.The brief of Ate Up With Motor is to discuss the history and design of interesting cars. That inevitably leaves you all at the mercy of what your author considers interesting, which bears some explanation.

Fish Story: The Plymouth Barracuda (Part Two)

When we last saw the Plymouth Barracuda, its second generation had floundered (if you’ll excuse the expression) in its efforts to challenge the popular Ford Mustang, ranking near the bottom of the “pony car” sales race despite more attractive styling and stronger engines. Troubled but undaunted, Plymouth took a third swing, with results that surprised even them. Here’s the story of Plymouth’s 1970-1974 E-body Barracuda and Plymouth Duster.

Fish Story: The Plymouth Barracuda (Part One)

If you ask the average person to name an American sporty car of the late sixties, you probably won’t hear “Plymouth Barracuda” unless the person is a dedicated Mopar fan. In a way, that’s curious, because the Barracuda was the first of the so-called pony cars to hit the market (even before the Ford Mustang) and in some areas it was arguably superior to its Ford rival. So, why was the Barracuda doomed to be a perennial also-ran? This is the sad story of the 1964-1969 Plymouth Barracuda.

CAFE and Cream: The Rules about Corporate Average Fuel Economy

There’s been a lot of talk in the U.S. in the past year or two about the prospect of raising the requirements for average fuel economy. Current plans call for raising that average from 27.5 to 35.7 mpg by 2015, which has caused considerable alarm in some quarters. To make sense of all this, let’s talk about how the corporate average fuel economy rules work, where they came from, and what they’re designed to do. Also, your author weighs in on the merits of these regulations.

Author’s Note: This article was written in 2009 and is now out of date — it has not yet been updated to reflect subsequent regulatory changes. Reader beware!

The Forgotten Ferrari: The Dino 308GT4

This week’s subject may be the most obscure of all Ferrari road cars. In fact, a fair number of histories of the marque omit it entirely — which is odd, because it was one of the best-selling cars Ferrari S.p.A. ever built. On the other hand, for the first few years of its existence, it was not officially a Ferrari at all. We’re talking about the often-overlooked Dino 308 GT4.

Doing the Twist: Horsepower, Torque, and Automotive Performance

One of the most confusing (and frequently contentious) questions in the automotive realm is the difference between horsepower and torque. You may have heard any number of pithy expressions, like “horsepower sells cars, but torque wins races,” or fans of big-engine muscle cars complaining that 200-horsepower four-cylinder engines are “gutless.” Surprisingly few of the worthies who throw around comments like that, though, are actually able to define the difference. What IS the difference between horsepower and torque, and what effect do they have on how a car performs?

Sadomasochistic: The Pleasures and Pains of the Citroën SM

Our more cosmopolitan readers are no doubt aware that “S/M” can be shorthand for sadomasochism (the enjoyment of inflicting and receiving pain). That alternate meaning makes the designation of the Citroen SM all the more piquant, for although the goal of this ne plus ultra of Citroens was high-speed comfort, its design was every bit as adventuresome (and as kinky) as the name implies. And, as we’ll see, it also involved more than a little pain for everyone involved.

Déesse Ex Machina: The Remarkable Citroen DS

The word “new” is much abused in the automotive business. If you believe the ad writers and press releases, cars are all-new almost every fall, but the reality is that most cars are the product of a gradual evolution stretching back decades. Well into the 1960s, there was little on the average car that would seriously puzzle a mechanic from before World War I. Every so often, though, an automaker takes the plunge on a design that really breaks the mold, a car like the Mini, the Corvair, or this one: the startling 1955-1975 Citroen DS.

The People’s Packard: The Packard One Twenty and How NOT to Build a Brand

The bread and butter of most modern luxury car companies is their “near-luxury” models, moderately priced but still expensive cars aimed at buyers who are enticed by the badge, but can’t afford the company’s real luxury cars. It’s big business today, but it’s not a new idea. Back in the mid-thirties, beleaguered Packard jumped into the mid-priced fray with its affordable One Twenty — the car that saved Packard and set the stage for its eventual demise.

Rocket Bomb: The Oldsmobile Rocket 88 and the Dawn of the American Horsepower Race

In the mid-1950s, American automakers were engaged in a ferocious horsepower race. By the time the battle reached a temporary ceasefire at decade’s end, the average power of the typical passenger car had (at least on paper) more than doubled. The starting gun of that race was sounded by Oldsmobile, with its advanced new overhead-valve V8 and the new mid-size model that shared its name: the 1949-1950 Oldsmobile Rocket 88.
