2020 Cadillac CT5-V, CT4-V to be revealed next week

Even though the ATS-V and CTS-V are on the way out, the future is looking bright for Cadillac's high-performance sub-brand. Why is that? Well we're going to see not one, but two all-new V models on May 30. The company revealed its plans to show the 2020 Cadillac CT5-V and the CT4-V in an announcement about 15 years of the V brand. Not much is known about either car, but both should be wickedly quick based on their predecessors. We're particularly curious as to what engines will be used. With the CT5-V, a return of a supercharged pushrod V8 seems possible considering the CT5 is based on the Alpha platform that also underpins the Camaro. But Cadillac may want to push its more unique powertrains such as the twin-turbo, double-overhead-cam 4.2-liter V8 in the CT6-V. In the CT6-V, it makes 550 horsepower and 627 pound-feet of torque. Cadillac's former CEO said that other cars getting the engine will have it 500 horsepower and 553 pound-feet of torque. We think the company could get away with the full power in the CT5-V, though, since each car's mission and character is different. There's also a slim chance we could see a return of the manual transmission for the midsize sports sedan, based on what a Cadillac engineer said. As for the CT4-V, there are more questions, simply because we haven't even seen the regular version yet except in spy shots. Since the CT5 is built off the Alpha platform, it seems reasonable to think the CT4 will do the same, especially since the ATS also used the platform. And to leave space between the CT5-V and itself, using a hot version of the twin-turbo 3.0-liter V6 seems like the most likely choice. The hot V6 in the ATS-V made 464 horsepower and 445 pound-feet of torque, so we would expect the same. Hopefully Cadillac will offer a manual with it again. One final note from the Cadillac V announcement also got our attention. It said that these two cars are "just the beginning." That seems a pretty obvious sign there are other V models in the works. Since the CT4 and CT5 will round out the company's car line, the logical next choice would probably be crossovers. It will be interesting to see what an XT4-V or XT5-V will be like, especially since they use front-drive platforms. But in the meantime, we'll look forward to Cadillac's hot sedans.

Cadillac tops Tesla in Consumer Reports semi-automated driving test

General Motors' Cadillac outscored Tesla in a new ranking of partially automated driving systems tested by Consumer Reports and released on Thursday. The highly influential nonprofit organization, which tests and rates a variety of consumer products from appliances to vehicles, said it compared Cadillac's Super Cruise and Tesla's Autopilot with similar systems from Nissan and Volvo. Nissan's ProPilot Assist was ranked third and Volvo's Pilot Assist fourth. Consumer Reports said it has been testing partially automated driving systems for several years but elected to conduct a formal study intended for publication, because "we are at a tipping point where they are now going mainstream," according to Jake Fisher, director of auto testing. The organization said its tests, conducted on a private track and on public roads in Connecticut, were designed to measure the systems' ability to automatically control steering and speed in certain situations, while helping drivers pay attention and regain manual control of the vehicle when required. CR noted that any of these systems can increase driving risk if used in inappropriate situations, or if drivers become inattentive or over-reliant on them. While they can help relieve driver stress and fatigue, Consumer Reports said, the partially automated systems are "not intended to be self-driving features." The systems typically use cameras, radar and other sensors, as well as mapping data, to monitor location and traffic conditions and help keep a vehicle centered in the lane at a safe distance behind other cars. Each system has limitations. Cadillac's Super Cruise, for instance, only functions on divided highways that have been mapped by GM. In contrast, Tesla's Autopilot can be used even on small, curvy roads with poor lane markings, but "operates erratically in those situations," Consumer Reports said.The organization tested Super Cruise on the Cadillac CT6; Autopilot on the Tesla Model 3, Model X and Model S; ProPilot Assist on the Nissan Leaf and Infiniti QX50; and Pilot Assist on the Volvo XC40 and XC60. Consumer Reports said Cadillac's Super Cruise did "the best job of balancing high-tech capabilities with ensuring the car is operated safely and the driver is paying attention." Tesla's Autopilot was cited for its capability and ease of use, while Nissan's ProPilot Assist did a better job than Autopilot or Volvo's Pilot Assist in keeping drivers engaged.

Junkyard Gem: 1981 Cadillac Eldorado with V8-6-4 engine

Skyrocketing fuel prices caused by geopolitical events in 1973 and 1979 led to gas lines, federal fuel economy requirements, and an increasing reluctance on the part of American car shoppers to buy big, thirsty Detroit luxury machines. General Motors had pulled off some amazing technological feats in the past — the small-block Chevrolet V8 engine and Hydramatic transmission being two extraordinarily successful ones — and so Cadillac's bosses figured that a combination of computer wizardry and clever mechanical engineering would give the 368-cubic-inch Cadillac V8 a cylinder-deactivation system and resulting superior fuel economy. Here's a very rare example of one of those 1981 Cadillacs, found in a California self-service wrecking yard. The idea behind the V8-6-4 was that computer-controlled solenoids would physically disengage the rocker arms for one or two cylinders on each engine bank under low-load conditions, converting the engine from a 368-cube V8 to a 276ci V6 or 184ci V4 (that's 6.0, 4.5 or 3.0 liters, respectively, for the metric-system aficionados among us). This sort of variable-displacement magic is commonplace today, but it was science-fiction stuff in 1981. An "MPG Sentinel" display on the dash would let the driver know how many cylinders were active at the moment, and the car would get Chevy Citation fuel economy with Cadillac luxury. The V8-6-4 was the standard engine in all 1981 Cadillacs (except for the Seville, which had the troubled Oldsmobile diesel engine as the base powerplant and the V8-6-4 as an option). Unfortunately, the V8-6-4 worked about as well as the Oldsmobile diesel: very poorly. Within a few years, most owners of these engines had disconnected the rocker-deactivation solenoids and just drove their cars as regular full-time V8s. This one has the snazzy "Cabriolet Roof Treatment" option, which boasted "textured elk grain" vinyl and could be had in one of 17 available colors. Front-wheel drive gave the early-1980s Eldorado plenty of interior space, despite its more proletarian Olds Toronado origins, and these velour-covered seats made for very comfortable road trips. The price tag started at $17,550, or about $51,650 in 2019 dollars. The 1981 Imperial went for $18,311, and that car was based on the same platform as the lowly Plymouth Volare. Meanwhile, A BMW 733i cost $28,945 and a new Toyota Cressida a mere $11,599. The 1981 Cadillacs were just a little too much ahead of their time, it turned out.
