New V6 engines are only the start at Cadillac

Cadillac debuted its new family of V6 engines Friday, but that's not all General Motors' luxury brand has in store for the coming years. The six-cylinder powerplants will certainly help Cadillac in the near term, but they're just two of the many parts of the company's future strategy. GM has invested $12 billion in Cadillac to help the brand grow over the next five years, and the company will launch eight new products between now and 2020. That all starts with the launch of the CT6 flagship later this year – a fullsize luxury sedan we'll see for the first time in New York on March 31. The CT6 will introduce several new features and technologies to the Cadillac range, and with its launch also begins the slow restructuring of Cadillac's model-naming system. The new nomenclature means CT and XT badges for cars and utilities, respectively. Cadillac says that of the eight new vehicles it plans to launch by 2020, five of them will be first-time offerings in market segments where the brand currently does not play. But it's not just about new products – new powertrains are an important part of the Cadillac story, too. After the new V6 engines – a naturally aspirated 3.6-liter and a twin-turbocharged 3.0-liter engine – launch later this year in the 2016 ATS, CTS and CT6, the company says it has a strategy for V8 power – possibly a twin-turbo application – as well as future electrification. Cadillac also says it's working on adding four- and six-cylinder diesel powertrains, though it's unclear which vehicles will make use of those engines. This new six-cylinder engine family is indeed important, with Cadillac's chief engineer, David Leone, calling it the "most advanced V6 in the industry." With 335 horsepower, the 3.6-liter engine is the highest output, naturally aspirated V6 powerplant Cadillac has done – and that's SAE-certified, and on regular fuel. Beyond that, the 3.0-liter mill (pictured at right) marks the first application of GM's active fuel management system on a twin-turbocharged engine. This means that when full power isn't necessary, the TTV6 can run as a 2.0-liter V4 in order to save fuel. New transmissions are also part of the V6 engine story. GM's all-new eight-speed Hydra-Matic 8L45 gearbox will be paired to the 3.6-liter V6, and the 3.0-liter TTV6 will use the company's existing 8L90 transmission that is already found in the Chevrolet Silverado and GMC Sierra pickups (with the 6.2-liter engine).

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Gimp Pimp and Aqua Volvo at 24 Hours of LeMons | Car Club USA

Car Club USA heads to Sonoma, CA where the Gimp Pimp Cadillac and Aqua Volvo will take on all the crazy, sub-$500 competition at the 24 Hours of LeMons endurance race. "Over the last 30 years, car racing has gotten extremely serious and extremely expensive and it just seemed like there was a real need to make it accessible again," said LeMons founder Jay Lamm. The result is a series of endurance races across the US and Australia where all you need to join the fun is a junky car and some basic safety equipment. "It's just fun, compared to pro racing," said Wendy Epstein, driver of a 1979 Volvo 242 in bright "Aqua Volvo" livery. "24 Hours of LeMons is a form of racing that is designed to be cheap and easy, and anybody can do it," said Bill Manfroy, driver of the Gimp Pimp, a 1996 Cadillac SLS with some important modifications. "Part of what makes the Gimp Pimp Cadillac so special is that it does have hand controls, so it gives access to people like me that ordinarily get to race." "Which makes it perfect for LeMons." Each Car Club USA episode features a different car club or event from across the US, where passionate owner communities gather to share automotive experiences and embark on incredible adventures.
