Cadillac CT5 spied with quad exhaust, could signal a hotter version is coming

The 2020 Cadillac CT5 just broke cover at the NY Auto Show this year, but one of our spy shooters caught one decked out in camouflage looking a bit different than the versions we've already seen. Instead of the dual exhaust on both the turbocharged four-cylinder and twin-turbo V6, this one has a quad exhaust outlet. We'll note that the placement of the quad outlets is one and the same with the two larger outlets on the CT5 already revealed. Also, the rest of the car looks relatively ho-hum. It has the wheels from the CT5 Sport trim, and the front end appears to most closely represent the Luxury trim. Some of the coverings appear to be opened up on that front end, possibly in an attempt to increase airflow. The most obvious change of them all is the quad exhaust, though, which brings us back to a conversation we had with a Cadillac representative at the car's initial media launch. As we were standing around gawking at the new CT5 in Sport trim, a brand representative told us all the "Sport" models (four-cylinders and V6s) would be getting quad exhaust, while the "Luxury" trims would get dual exhaust. We pointed at the CT5 Sport right in front of us and noted that it just had a dual exhaust setup. This ended up causing more confusion, as the Cadillac representative was adamant that they had seen the CT5 Sport with quad exhaust. When all was said and done, there wasn't exactly a clear explanation given for what was up with this mysterious CT5 model with quad exhaust, so we left it at that. We can guess, though. Perhaps the Cadillac rep had seen a Sport model with quad exhaust, but it was a future "V-Sport" variant we weren't allowed to know of yet. Cadillac hasn't revealed its future plans for the CT5 fully, but it did hint that at least one performance variant would be on the way. This camo'd up car here does not look anything like a full-on V model, but it could be the beginnings of a slightly more powerful version of the sport sedan. The 3.0-liter twin-turbo V6 makes 335 horsepower and 400 pound-feet of torque. Of course, there's always room for more power in this class, and a V-Sport model would slot in nicely to the new sedan's range. Keep in mind this all remains speculative in nature. However, our curious conversation with Cadillac combined with these spy shots signal that something could be afoot.

How Cadillac improved power output in 2016 ELR by 25 percent

Earlier this year, Cadillac announced that the 2016 ELR would come with a big price drop and a powertrain that packs 25 percent more power output. That's a lot more oomph, but it didn't sound like the Caddy engineers made any major changes to the engine or motors. So, what happened? Let's refresh our memories with the numeric details. The 2016 car is 1.5 seconds quicker to 60 miles per hour than the 2014 model (there was no 2015), down to 6.4 seconds. The 2014 put out 295 pound-feet of torque. For 2016, it will be 373 lb-ft. The specific breakdown of the various components in the powertrain has not been disclosed, but from what we can tell, the two electric motors and the 1.4-liter inline-four engine in the new ELR are not that much different than those in the old one. Sam Abuelsamid, senior research analyst at Navigant Research (and former writer here at Autoblog) said that any of the unspecified upgrades would be difficult to tell on a part-by-part basis, but the overall effect will be noticeable. "The changes to the ELR as I understand them are analogous to getting more performance out of a 1965 Mustang with the entry version of the 289 cubic-inch V8. You can replace the carburetor with a larger version that enables more air and fuel to flow into the engine, thus producing more power. The basic engine hasn't changed, but power capability is being unleashed by feeding it more." "Cadillac has changed components in the power electronics to enable more current flow into the motor and thus produce more torque. When you do this in the Mustang, you probably need to replace the rear axle gears and use a beefier clutch to transmit the power to the wheels. Similarly, the ELR probably has some upgraded clutches, bearings, and gears to withstand the increased total output." Cadillac spokesperson David Caldwell told AutoblogGreen in an email that the new ELR does indeed have more than just new lines of code. "One could not 'reflash' a previous ELR to get the performance of a 2016," Caldwell said. "If one only changed software you would not get the performance upgrade fully, as the 2016 creates higher current, more power. So these have been upgraded physically – hardware.

Junkyard Gem: 1993 Cadillac Allante

The General's Cadillac Division had lost much of its status as a world-class styling and engineering innovator by the 1980s, while younger rich Americans signed on the line which is dotted for European luxury machines packed full of futuristic technology. Something needed to be done to win back the hearts of those buyers, and that something was the Cadillac Allante two-seater. Here's a final-model-year Allante, complete with one of the very first Northstar V8 engines, found in a Denver yard. The overhead-valve Cadillac V8 engine of 1949 shook up the automotive world, and the double-overhead-cam Northstar V8 of 44 years later had a similar effect. Finally, a high-revving, smooth-running modern V8 to compete with those pesky European and Japanese carmakers! Only the Allante got the Northstar at first, with other Cadillac models following soon after. After the underwhelming power output of the pushrod HT4100 V8s used in the 1987-1992 Allantes, the upgrade from 200 horses to 290 helped boost sales of the '93 to the highest annual figure ever achieved by the model: 4,670 cars. Unfortunately for GM, production costs of the Allante proved to be murderous in the long run. Shortened Eldorado frames were loaded onto specially-fitted 747s in Detroit and flown to Pininfarina's new Allante factory in Italy. After Pininfarina built the bodies, they got loaded onto the 747s, flown back to Detroit, trucked to the Hamtramck assembly plant, and given running gear there. GM called this system the "Allante Air Bridge" and it cost plenty. The cars looked both futuristic and Italian, which they were, but the Allante's price tag stood at heights far above those of the rest of the Cadillac line: $59,975 in 1993, or about $108,500 in 2020 dollars. You could buy a rear-wheel-drive BMW 850Ci with a 282-horse V8 and manual transmission for a mere 10 grand over the Allante's cost that year, or a Jaguar XJS convertible for just $56,750. The Allante had front-wheel-drive and a not-so-modern four-speed automatic transmission, which hurt sales among the enthusiast types who flocked to Cadillac showrooms for the CTS-V a decade or so later. No European machine of 1993 could top the Mars Base appearance of these vertically-arranged, all-pushbutton HVAC/audio controls, though.
