In his New York Times comparison of heavy-duty pickup trucks, Ezra Dyer opens with a provocative comparison:

Heavy-Duty pickup trucks are the supercars of the truck world. They have more power than drivers are likely ever to exploit, and bragging rights depend on statistics that are, in practical terms, theoretical.

How does he figure?

While you can’t buy a diesel engine in a mainstream light-duty pickup, heavy-duty pickups now offer propulsion suitable for a tandem-axle dump truck.

I’m not exaggerating. Ford’s 6.7-liter Power Stroke diesel V-8 packs 400 horsepower and 800 pound-feet of torque; the base engine in a Peterbilt 348 dump truck offers a mere 260 horsepower and 660 pound feet. Does your pickup really need more power than a Peterbilt?

I’m guessing most HD truck owners won’t take kindly to the question, especially coming a scolding Gray Lady. But if you read the full review, you’ll find that Dyer was able to locate at least one contractor willing to admit that he realized he just didn’t need his HD’s overabundance of ability. It goes against the grain of the “bigger, faster, tougher, more” marketing message that has helped make trucks such a huge part of the American market, but is it possible that the tide is turning? Have pickups improved too much? The huge sales of Ecoboost V6-powered F-Series certainly suggests the we may just be moving towards a more pragmatic truck-buying market…

The Truth About Cars presents news and opinion in an informal, conversational manner. As the site’s freshly anointed copy editor, preserving this style without being too anal retentive is a real challenge. I keep telling myself not to adhere to the rules of formal writing (Strunk & White be damned). This is a new age. The old styles aren’t always appropriate for Web 2.x (and beyond). This internal struggle informs my desire to write the official TTAC style guide. I’m trying to reconcile our contributors’ literary voices with necessary structure and, this is the important bit, community consensus. I want to give TTAC a distinctive, consistent voice in the autoblogosphere, during a time of uncertainty and change. I need your help.

Let’s begin this journey with torque and horsepower; twist and ponies. While I don’t want to reduce TTAC writers’ freedom to describe a car’s thrust, something must be done about the use of engine-related statistics on this site.

Recently, TTAC contributor Jonny Lieberman co-opted Jeremy Clarkson’s use of the word “torques.” Our left coaster did it twice, clearly intending the term to replace “lb/ft” or “pound-feet of torque.” Not to mention, Farago’s recently abandoned, UK-centric “ft.-lbs.”

The newly christened nickname certainly sounds faddish. To some, it’s an overly familiar affectation. “The Porsche Carrera GT has 435 torques.” That said, plenty of pistonheads use “ponies” or “horses” in place of “horsepower.”

Be that as it may, Jonny’s assault on my anal retentive nature underscores the need to agree on a house style for the stat: a standard technical designation for an engine’s torque.  So, what should it be: lb/ft or pound-feet or foot pounds or ft-lbs. or something else?

If only it were that easy…

Next, should we list the rpm at which maximum torque arrives? “The Porsche Carrera’s V10 delivers 435 ft lbs @ 5750 rpm” as opposed to “The Porsche Carrera’s V10 develops 435 torques?” [NB: don't get me started on "develops," "stumps up," "generates," and so forth.]

Keep in mind that TTAC reviewers butt up against an 800-word limit. Every word—and number—counts.

Just to make matters that much more complicated, what about Newton meters?

TTAC has a global audience, many of whom use the metric system. Should we offer both lb/ft (or whatever) and Newton meters? If we do use Newton meters, should we use the formal “Newton meters” or “N-m” or (and I’m kidding here) just use “newts?”

Horsepower is not as straightforward as it sounds. We can choose between HP and hp and a space between the number and numerical statistic, or not. “The Carrera GT’s engine is good for 605 hp” or “The Carrera GT’s engine is good for 605hp” or “The Carrera GT’s engine is good for 605 HP.”

Again, metric issues arise: kilowatts! Should we go there? If we offer newts, why not kwatts?

And if we do do that voodoo that kilowatts do, should it be “KW” or “kw,” space or no space? And if we offer an rpm arrival point for maximum torque, why not horsepower? For example, “The lightweight Porsche Carrera GT has tremendous torque (589.78 nm / 435 ft lbs @ 5750 rpm) and prodigious power (451.2 kw / 605 bhp @ 8000 rpm).” I’ve got a headache…

The alternatives don’t stop there. We could prevent an international incident with a hover hack: readers could mouse over the U.S. ratings (or not) to discover the equivalent metric amount.  Or we could add a horsepower and torque box with the stars and stats and not worry about numbers in the actual review. And finally…

We could drop the whole thing. RF figures TTAC’s not Car and Driver. “We’re trying to convey the soul of a machine. We’re not under no obligation to provide ANY statistics.” Thanks for that, boss. But if we do offer engine output numbers—and you know we will—TTAC should do so with logic, clarity and complete consistency. Please, help me in this quest by taking this survey.
