Cadillac to Corvette: You’re not getting our twin-turbo V8 engine

NEW YORK — Cadillac president Johan de Nysschen bluntly shot down rumors his brand's powerful twin-turbo V8 is also headed for the Chevy Corvette. Speaking Wednesday at the New York Auto Show, he said: "Just quit the speculation it's headed for Corvette. It's not." The 4.2-liter V8 cranks out 550 horsepower and 627 pound-feet of torque in the Cadillac CT6 V-Sport, which debuted at the show. With that kind of performance and the fact the engine will be hand-built at the General Motors Performance Build Center in Bowling Green, Ky. — at the Corvette factory — led enthusiasts to presume the engine would eventually be under the Vette's hood. De Nysschen, however, argued the engine will also focus on levels of refinement, rather than the Corvette's raw, visceral dynamic. "I think Corvette wants a different kind of character," he said. In fact, the V8 is set to be only for Cadillacs, de Nysschen said, giving the luxury brand its first exclusive engine in years. "It's a matter of being a thoroughbred luxury car," he said. "It's really only a luxury brand that could recoup this [development] cost." A version of the engine making 500 hp and 553 lb-ft will also be used in other Cadillac models. De Nysschen declined say which vehicle will get the engine next. The new V8 uses a "Hot V" configuration more common to German performance cars, and has direct injection, electronic wastegate control, active-fuel management and stop-start technology. It teams with a 10-speed automatic transmission and fits either rear- or all-wheel drive systems. With a new mid-engine Corvette — and potentially more versions of the existing generation Vette — on the horizon, speculation pointed to the sports car getting a twin-turbo powerplant of some sort (V6 rumors also have floated), and the Cadillac 4.2-liter seemed to fit on paper. According to de Nysschen, that won't be the case. Still, even though the Cadillac boss says this specific engine won't go to Corvette, it's hard to not think some version of this engine, perhaps in a different displacement, could find its way under the hood of the Vette at some point in the future.

GM recalls 2022 Cadillac XT5, XT6 and GMC Acadia for suspension issue

General Motors is recalling a relatively small number of 2022 Cadillac and GMC crossovers to address the potential for missing or loose rear suspension hardware that is being blamed on a lapse in quality control at the company's Spring Hill facility. The campaign covers 223 examples of the Cadillac XT5, 159 examples of the Cadillac XT6 and 354 examples of the GMC Acadia. "General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2022 model year Cadillac XT5, XT6, and GMC Acadia vehicles," GM said in its defect report. "A fastener in the left-rear suspension toe link in some of these vehicles may not have been fully tightened during suspension assembly. After an assembly process was moved to a new area, error proofing equipment was not initially set up properly, which allowed a window where the operator might miss tightening certain fasteners without the failure being flagged." The issue was discovered by a quality engineer at the Spring Hill facility in March of this year, at which point GM conducted an audit to determine which and how many vehicles may have left the factory with improperly torqued or missing fasteners, narrowing down the recall population to the above 736 vehicles. No incidents associated with the defect have been reported in customer vehicles.  Related video: Recalls Buick Cadillac GM Ownership Safety
