While Mercedes-Benz has gradually been moving away from larger motors, it was still a shock to learn that the company would be removing the brunt of its V8-powered lineup in the United States for the 2022 model year. Higher-end vehicles typically come with broader profit margins and Americans tend to like V8s, so it was strange to see the brand tailoring its product at the last minute. Less surprising, however, was watching the entire automotive community speculate on the reasons why.

As your author is constantly suspect of regulations, it was my assumption that emissions compliance was the main culprit. But one would assume European rules would have put the kibosh on V8s in the home market long before cars were neutered in North America. Mercedes likewise suggested this was not the case, alluding to supply chain issues that have been hampering the industry since the start of 2020 while it promised to fix the problem as soon as possible. Then, Daimler executives started giving different answers and hit the reset button on the global supposition surrounding the discontinued engines.  (Read More…)

The 2021 Acura TLX Type S is currently being shined up in showrooms around the country in the hopes of catching the eye of people that still remember the brand formerly produced a handful of downright excellent performance vehicles. It’s specifically trying to recapture the magic of the TSX — which the rest of the world knew as the fun version of the Honda Accord — and appears to have been built under a similar philosophy.

Rather than committing itself to ludicrous levels of power or an overabundance of attitude, Acura has attempted to deliver a balanced, tasteful luxury vehicle that can still scramble like an egg. While the previous offspring of this mindset made do with roughly 200 horsepower, the TLX Type S produces a much more meaty 355 horsepower and 354 pound-feet of torque and recently dropped some additional marketing materials to drive that point home now that it’s on sale.  (Read More…)

General Motors will reportedly be making a $75 million investment into Toledo Transmission later this year. This follows an earlier $39 million investment from GM set aside for the eight-speed rear-wheel-drive transmission, which came as a package deal offering another $32 million for Defiance Casting Operations.  (Read More…)

While working on a story about some very old cars, I stumbled upon something relevant to the latest big story in the automotive world.

I ran into a Model T collector who’s also a powertrain engineer for Ford. Seizing the opportunity, I asked him if he could tell me what he was working on (sometimes they say no). He said that he was responsible for developing computerized engine controls. Because of that expertise, I started to ask him some questions about the software program that Volkswagen apparently used to cheat on the EPA’s diesel emissions testing.

What he was willing to say and what he wouldn’t say intrigued me. (Read More…)

According to Germany’s Bild tabloid, the next Volkswagen personnel to be shown the door could be three people integral to powertrain development during the time when vehicles were fitted with “defeat devices”.

Prof. Dr.-Ing. Ulrich Hackenberg, Audi Board Member for Technical Development; Wolfgang Hatz, Porsche Board of Management; and Dr. Heinz-Jakob Neußer, Head of Powertrain Development at the Volkswagen Group are rumored to be the next executives and managers to be fired, though a final decision won’t be made until Friday.

Hi again Sajeev,

Steven Lang’s post buying quality tools piked my interest again on getting myself an OBDII scanner. But which one is right for me? Even the Autel brand mentioned by Steve have readers ranging from $30 to the $350 Autel MD802 mentioned in Steve’s post.

I don’t plan on working on my cars much, just want to use more than onomatopoeias to converse with my mechanics. (Nice. – SM) (Read More…)

Mircea Gradu, who had headed Chrysler’s transmission, powertrain and driveline engineering since 2011, left the company to pursue other interests, according to a company statement released last week. Part of Gradu’s responsibilities were the development and launch of the new Jeep Cherokee’s innovative all wheel drive system that can allow the rear axle to freewheel to save fuel. That launch was delayed when 25,000 assembled Cherokees were held back from dealers while engineers recalibrated the software that controls the powertrain and then tested the vehicles. The same basic drivetrain components are planned to be used in a number of other Chrysler group vehicles, starting with the all new 2015 Chrysler 200 introduced last week at the Detroit auto show.
