2020 Cadillac CT4-V First Drive | The Cadillac of compact Cadillacs

With the launch of the 2020 Cadillac CT4, GM is pushing back into the smallest luxury sedan segment that in recent years has almost exclusively featured entries from Germany. We're pleased to see it return, and importantly, that it definitely came back prepared. The CT4’s key differentiator is its platform. Unlike the bulk of entry-level luxury sedans currently on the market, the Cadillac rides on a rear-wheel-drive platform. All-wheel drive is available throughout the lineup for those who need (or just want) four-season flexibility, but itÂ’s meant to be a convenience feature rather than a performance upgrade — the same is not true of its front-wheel-drive competitors. The CT4 ostensibly replaces the discontinued ATS, but reality is a bit murkier than that. Stop us if youÂ’ve heard this before, but the Cadillac CT4 is not entirely size-appropriate for the class. While the CT4 is aimed at the subcompact luxury sedan segment (and the CT5 at the compact), itÂ’s dimensionally a bit closer to the likes of the Mercedes C-Class than it is the A-Class. This gives Caddy a bit of an advantage, but itÂ’s nothing we havenÂ’t seen from GMÂ’s luxury arm before. Cadillac has chosen instead to target the segment based on price, which is a win for consumers in a way, as you can get a little bit more bang for your buck if theyÂ’re willing to take a chance on the underdog. Cadillac is offering its new small sedan in three states of tune. The base (“Luxury”) model boasts a 2.0-liter engine good for 237 horsepower and 258 pound-feet of torque. The Premium Luxury and CT4-V models get the 2.7-liter — which is still a four-cylinder — that makes 310 hp and 350 lb-ft of torque in its base tune and 325 hp and 380 lb-ft in the CT4-V. All three variants make use of GMÂ’s active fuel management tech which allows them to run on just two cylinders to conserve fuel while cruising. Yes, you read that correctly. The CT4-V boasts just 325 hp, which may seem like a pittance considering the outrageously powerful V models of CadillacÂ’s past, but GMÂ’s luxury arm has decided to re-jigger its performance hierarchy by eliminating “V-Sport” entirely, shifting “V” down to fill that role, and introducing a series of new range-topping performance models dubbed “Blackwing.” In that context, the CT4-V may seem like an also-ran, but consider the company it keeps.

Why an independent rear suspension for GM's new, full-sized SUVs wasn't easy

A Motor Trend report last month laid out how Cadillac's 4.2-lier twin-turbo Blackwing V8 could be an orphan due to cost concerns in the GM empire. Last-minute chassis changes to Cadillac's new sedans and XT6 crossover led to engine bays that couldn't fit the Blackwing. On the SUV side, according to the report, the new independent rear suspension for big people haulers cost so much to implement that GM ruled out reworking the Escalade to accept the Blackwing. At least one commenter rightly asked how could a suspension swallow that much money. A new piece in Motor Trend has the answer. The excellent Alissa Priddle spoke to Tim Herrick, GM's executive chief engineer for full-size trucks, about why the clean-sheet IRS cost "multimillions of dollars."  First, GM would need to build a new body shop at the Arlington, Texas plant that assembles the automaker's big SUVs to stamp the numerous wholly new parts and panels accommodating an IRS. Then GM would need to design and pay for a new assembly process. On top of those up-front costs, there was the incremental cost of the four-link IRS components being more expensive than those in the trucks' former leaf-sprung solid axles. Herrick endured so many rejections for so long that he remembers the date and time when he got approval for the new unit. He said it came down to a meeting where he told a higher-up, "I'll make you a deal: If we get to the reveal, or if we launch this and you think this was a dumb idea, I'll hand you my badge and let you walk me out." Head to Motor Trend to read the full story. Based on Herrick being on stage to help present the new SUVs to the press, and on our First Ride in the new Chevrolet Tahoe and Suburban at GM's Milford Proving Grounds, it appears this will have a happy ending for all involved. Furthermore, since Herrick worked on the T1 platform that supports the big SUVs as well as the light- and heavy-duty pickups, he understood the demands on the commercial side, too. That could be why when Roadshow asked Tim Asoklis, chief engineer of the Tahoe and Suburban, if the new IRS could endure life in the Chevrolet Silverado and GMC Sierra, Asoklis answered, "Oh, absolutely."

Hennessy wastes no time in supercharging the 2015 Cadillac Escalade

The ink is still drying on the all-new 2015 Cadillac Escalade sales brochures, but that hasn't stopped Texas-based Hennessey Performance (HPE) from leaping out of the gate with its own high-performance variant. In stock form, the big fourth-generation Cadillac flagship arrives with a new small block naturally aspirated 6.2-liter Ecotec3 V8 delivering 420 horsepower and 460 pound-feet of torque. Fresh out of the showroom, the 5,900-pound SUV will sprint to 60 mph in 5.9 seconds.
While that is plenty fast for some owners, others don't want to be shamed by a 550 horsepower Mercedes-Benz GL63 AMG or a 510 horsepower Land Rover Range Rover Sport - both will leave the stock Escalade at a stoplight.
The team at HPE has come to the rescue with its HPE550 supercharger upgrade, which includes a belt-driven supercharger, air-to-water intercooler, recalibrated engine management software and a three-year/36,000 mile powertrain warranty. With 6 psi of boost, the direct-injected 6.2-liter is tuned to deliver an impressive 557 horsepower and 542 pound-feet of torque - gains of 32 percent and 18 percent, respectively, over stock. Although HPE isn't releasing performance figures as of yet, our math says that should be enough power to put the two Europeans in the Cadillac's rearview mirror. The company also offers a set of 20-inch lightweight H10 forged monoblock wheels, to further improve performance.
