Our Abandoned History coverage of the Turbo-Hydramatic transmission series continues today. The THM was a singular solution to two different automatic transmissions in use by Oldsmobile, Cadillac, and Buick in 1963. Turbo-Hydramatic arrived at a time of modernization for the automatic, which prior to the mid-Sixties was regarded as inefficient and less than smooth.

The THM400 was the 1964 replacement for the Hydra-Matic and Buick’s Dynaflow and established itself as a smooth and reliable gearbox. It proved useful in a variety of luxury and heavy-duty applications and shrugged off weight and torque easily. In short order, it took off as the transmission of choice for various small manufacturers outside of GM. However, no matter how excellent the THM400 was, it found itself squeezed by a drive toward greater fuel efficiency. It was also a bit hefty to be of broad use in smaller or lighter passenger cars. GM needed more Turbo-Hydramatics!

A few weeks ago, we concluded Abandoned History’s two-part coverage of the Chrysler UltraDrive transmission. Within the comments was a request for more transmission coverage of an equally abandoned nature. Let it be so! Come along as we discuss the vast automatically shifted expanse that was the Turbo-Hydramatic transmission family, by General Motors.

We finish up our Abandoned History coverage of the long-lived UltraDrive transmission today. The pursuit of simplification, modernization, less weight, and better fuel economy lead to the creation of the electronically controlled four-speed A604 marketed as UltraDrive. The idea floated around at Chrysler in the Seventies and then was greenlit and put into production (before it was ready) by an eager Lee Iacocca. A case of unfortunate timing, the new transmission arrived in 1989 at a time when there was almost no exciting news in Chrysler’s product portfolio. Thus the UltraDrive name was coined by marketing, and the new and advanced transmission was featured heavily in the company’s PR materials in 1989 and 1990.

The UltraDrive’s debut version was prone to numerous types of failures because of fluids and sensors, build quality, parts, really everything. But engineers at Chrysler quickly massaged the A604 into the improved 41TE that was ready for use midway through the 1990 build year. UltraDrive was up and running within acceptable reliability standards per Chrysler. Clearly, it was time to create more UltraDrive variations!

The recent Rare Rides Icons post on the 1990 Chrysler Imperial Super-K Gingerbread Cookie Edition generated a few comments not only about the subject in question but its four-speed UltraDrive transmission. It seems more than one of you wants a discussion – no – an essay on the UltraDrive. Wish granted! Here we go.

Mercedes-Benz SLThe 2022 Mercedes-Benz SL is a timed release. Its dramatic entrance will come before the end of 2021. Before its arrival, will you tire of it, or be that much more enthralled?

Previously, we saw SL prototypes drifting in the snow, showing off their all-wheel drive (AWD) capabilities. Now the automaker wants you to see beneath the surface, reinforcing the rigidity of its composite aluminum structure.

When you think about V6 engines, you’re probably reminded of mainstream family vehicles and manufacturers trying to find a way to package six cylinders in the most efficient manner. Inline sixes are great, but their length makes them difficult to install in the bulk of a manufacturer’s lineup. By splitting the cylinder count into two banks, the V6 avoids this problem — which is why you’ve seen it in everything from minivans to supercars over the last few decades.

Even Aston Martin has decided to tap the configuration for its next generation of vehicles. Developed in-house and intended for hybridization, the automaker promises its new V6 will not only live up to expectations but surpass them by outperforming the mightiest V12 in its stable. That 5.2-liter motor currently belongs to the Aston Martin DBS Superleggera and makes 715 horsepower and 664 lb-ft of torque.  (Read More…)

Despite delivering what could be considered a desirable premium EV with the I-Pace, Jaguar Land Rover admits it’s not entirely sold on the idea of electric sport utility vehicles. Due to their size, SUVs and crossovers are inherently heavier than traditional sedans — placing them at odds with the goal of maximizing efficiency.

More mass means diminished range. While this can be offset by a manufacturer installing larger battery packs, that increases costs and ultimately adds more heft to the single heaviest component in an EV. Large electrics bring other issues to the engineering table, too.

“The larger the vehicle the larger the aero challenge. If you’re not careful you end up with such big batteries and you make the vehicles so heavy that as you race down the autobahn the range disappears,” Nick Rogers, JLR’s head of engineering, told media at the company’s revamped engineering and design center in Gaydon, England.

The first thing that many people do when their new car is ready for its first set of replacement tires is to ditch them for something else. Whether that’s a tire with a high tread mileage guarantee, an ultra-grippy tire, or the cheapest thing they can find, few people actively seek out the exact same tires that their vehicle came with from the factory.

If OEMs could have just selected the best-rated tire from the Tire Rack website, or asked people on a forum what they preferred, and called it a day, wouldn’t they have done that? If you think you’re smarter than an entire team of OEM engineers, then go ahead and slap on that 80,0000-mile-guaranteed set of tires. But, you will want to understand what you might be giving up in the process. (Read More…)

As per its $11 billion investment in electrification, Ford intends to have 40 electrified vehicles — 16 of which will be battery-only — on sale by 2022. That includes the widespread hybridization of trucks, crossovers, and SUVs. As towing has not historically been a great strength of hybrids, the automaker is developing a new transmission system it calls “modular hybrid technology.”

The system, which debuts on the 2020 Explorer, is said to incorporate an electric motor, clutch and torque converter to help vehicles deliver superior fuel economy without sabotaging a vehicle’s ability to haul ass or whatever customers choose to hitch up behind the tailgate.  (Read More…)

Even with affordable electric vehicles cropping up on the global market, their budgetary nature is relative. While the industry promises that EVs will offer the world an affordable, mechanically simple and green alternative to traditional internal combustion models, they’ve yet to deliver. That’s not to suggest e-cars are failures, just that the technologies involved are still maturing.

Battery prices will continue to decline and eventually governments won’t always need to incentivize EV purchases through tax credits. But we’ve yet to reach the point where it makes just as much financial sense to buy a small EV as it would a gasoline-powered econobox. That could soon change. (Read More…)

1978 buick rega turbo v6 engine

If you’re the type of automotive enthusiast who covets cylinder volume above all else, this probably hasn’t been your decade. However, if you’re of the boosted breed, things couldn’t be better. Forced induction engines are bigger than ever, not in size (again, sorry displacement fans) but in factory application.

The numbers of turbocharged vehicles sold in the U.S. rose for a sixth consecutive year in 2017, now accounting for 27.6 percent of new cars and light truck models built through March 2017. For the sake of reference, the 2011 model year only saw 10.7 percent, while previous years loitered between 4.5 and 6.6 percent annually. This makes turbocharging less of a trend and more of a revolution.  (Read More…)

tesla factory fremont

Tesla Motors is headhunting engineers from Mexico to work on automated equipment at its Freemont, California factory. While the brand can still call the forthcoming Model 3 “the most American” car in the world — once it takes delivery of Nevada-produced 2170 battery packs — it might not be able to make the same claim for its workforce.

The brand has had union troubles with the German robotics unit supplying the automated assembly lines essential for the Model 3’s timely production. While the recruitment effort in California may not be a direct response to that, it is definitely part of Tesla’s efforts to ensure it can adhere to the timetable it has set for the electric vehicle. The company has preorders out the wazoo and wants to build 500,000 cars a year at the Fremont plant by 2018, which requires a sextupling of 2016’s production figures.  (Read More…)

One of the first things you notice in the silence of an electric car is how prevalent wind and tire noise can be without an internal combustion engine to breakup the aural monotony. While no one has ever slipped into madness due to an overabundance of road noise, rubber grinding against concrete at seventy-five miles an hour isn’t the most pleasant sound in the world, either.

Lucid Motors promised that its upcoming Air EV would possess an audio system equipped with active noise cancellation to ensure that its interior remains a silent space. However, we are only just now discovering how seriously they took that promise. (Read More…)
