We won’t bore you with a rehash of the upgrades and advancements bestowed upon the 2018 Dodge Challenger SRT Demon, because we already did that last week.

With the ultimate Mopar muscle machine now exposed at the New York International Auto Show, those advancements — and the speculation surrounding the vehicle’s unknowns — fade in comparison to newly released numbers. Power and acceleration figures, to be exact.

This time, the speculation was largely wrong, as the Demon makes more horsepower than we thought. So powerful is this limited-edition beast, it has already been banned from National Hot Rod Association dragstrips.

When a self-described automotive journalist attempts a fuel economy record, you expect his attempt to be objective — or, at least, as objective as such an attempt can be.

However, when an automaker is willing to pay that automotive journalist thousands of dollars for the effort, with payment possibly dependent on achieving the desired record, objectivity falls by the wayside and, along with it, the credibility of someone believed to be a hero in high-fuel-efficiency circles.

Wayne Gerdes, if you aren’t familiar, owns a website called CleanMPG.com. It’s a forum dedicated to those squeezing every bit of fuel efficiency possible from their vehicles — also known as “hypermiling.”

Automotive journalist Gerdes set two records — in 2013 and 2015 — using Volkswagen TDI Clean Diesels. In doing so, the journalist lined his pockets with Volkswagen’s marketing cash.
