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.

Our favorite mid-engine Corvette theories and rumors

The mid-engine Corvette! We just saw blurry photos through the foliage, and are hearts are all aflutter because it means that this car is real. And it's the most " never before" Corvette since 1984. Which leads us to all kinds of wacky theories and speculation. Everybody knows something or heard from a guy. None of those guys (or gals) from GM are talking to Autoblog, to be clear. But that won't stop us from stirring the pot. Let's go over a few point-by-point. The pushrod engine will be replaced by an overhead-cam V8 Car and Driver has repeatedly reported that an overhead-cam engine will come after the mid-engine Corvette's debut with an old-school pushrod. We've heard the same thing firsthand, albeit from a source with no connection to the development of the Corvette or powertrain. "At some point two valves can't pass future emissions regulations," said the guy we know. While the pushrod engine is compact, the design makes it difficult - if not impossible - for sophisticated variable valve timing (and lift) systems that control combustion with more precision. Hasty conclusion: The pushrod engine has a finite life in front of it. This one's a lock, it's a just a matter of when. Bowling Green's new paint shop is really the mid-engine assembly line Credit to Reddit for this one. Like we said, everybody knows a guy. But let's look deeper. The new paint facility costs $439 million dollars and adds 450,000 square feet, almost half the size of the existing plant. Plus GM announced another $290 million in upgrades at Bowling Green Assembly. That sure sounds like a lot of money, but you can actually spend that much on a paint booth. Porsche spent 500 million Euros (about $561 million dollars) to add the Macan assembly to its Leipzig, Germany plant in 2014. Chrysler shelled out $850 million for a paint shop in Sterling Heights, Michigan. GM spent $600 million for a new paint shop at the Fairfax (Kansas City) plant. Honda, on the other hand, is working on a thrifty $210 million project in Marysville, Ohio that includes a 300,000 square foot expansion, and the low-volume Acura NSX facility only cost $70 million. Hasty conclusion: The square footage and cost could easily mean a new assembly line instead of (or in addition to) a paint line. And if the NSX plant was really that cheap, GM could have hidden a similar sum in its existing announcements.

The biggest gas-guzzlers of 2024: 'The Meanest List' is the opposite of greenest cars

In some circles — especially some automotive circles — bigger is better. This explains the Hummer, for example. In its so-called “Meanest List” of a dozen models, the American Council for an Energy-Efficient Economy (ACEEE) makes no apologies for berating “the worst-performing mass market automobiles” sold in 2024 in the U.S. The most diminutive car on the list is a Chevy Corvette Z06. At the top of this particular heap is the Mercedes-Benz AMG G63, a gas-powered SUV that the environmental agency says was “the worst-performing vehicle of the more than 1,200 models assessed by Greener Cars and has an annual fuel cost over $4,000.” Not to mention its MSRP of around $184,000. Rank Make & Model Powertrain Green Score MSRP Estimated Annual Fuel Cost* 1 Mercedes-Benz AMG G63 Gas 20 $184,000 $4,242 2 Ram 1500 TRX 4x4 Gas 22 $98,335 $3,819 3 Ford F150 Raptor R Gas 24 $79,975 $3,777 4 Cadillac Escalade V Gas 26 $152,295 $3,388 5 Dodge Durango SRT Gas 26 $74,995 $3,332 6 Jeep Wrangler 4dr 4X4 Gas 27 $35,895 $3,260 7 Jeep Grand Wagoneer 4x4 Gas 28 $91,945 $3,058 8 Mercedes-Benz G550 Gas 28 $143,000 $3,186 9 GMC Hummer EV SUV EV 29 $98,845 $1,746 10 GMC Sierra Gas 29 $37,700 $3,069 11 Chevrolet Corvette Z06 Gas 30 $114,395 $3,169 12 Mercedes-Benz Maybach S680 Gas 30 $234,300 $3,031 *ACEEE analysis using EIA data of the annual cost of driving 15,000 miles In terms of numbers, the dirty dozen of the meanest includes seven SUVs and three trucks. Lonely at the middle of the list is the sole electric, the GMC Hummer EV, which weighs in at 9,000 pounds. The council notes that “though EVs have lower emissions than similarly sized gasoline models, the Hummer demonstrates that size and efficiency, not just fuel source, are important factors in a carÂ’s environmental impact.” ItÂ’s also worth reminding prospective buyers that the average fuel cost of a vehicle on the “Greenest List” eats up only a fifth of the fuel cost of a vehicle on the Meanest List, “showing that greener options can also be more affordable.” The ACEEE also put out a "Greener List" of efficient gasoline and hybrid cars that don't require plugging in.  By the Numbers Green Cadillac Chevrolet Dodge Ford GMC Hummer Jeep Maybach Mercedes-Benz RAM Emissions Fuel Efficiency Green Automakers Truck SUV Electric Hybrid
