GM to accelerate its EV strategy — Cadillac could be all-electric by 2025

General Motors will roll out details of an expanded and accelerated electric vehicle strategy on Thursday in an effort to convince investors it can be a serious competitor to Tesla, people familiar with the plans said. GM Chief Executive Mary Barra, who is scheduled to speak at a conference hosted by Barclays, is expected to say the automaker is ready to spend more on electric models by 2025 than the $20 billion previously outlined, the sources said. Supplier sources said previous plans to make the Cadillac brand all-electric by 2030 are being sped up, possibly to 2025, and other sources said that acceleration will be repeated in other brands and in segments such as commercial vans. Asked about the Thursday appearance, a GM spokeswoman called talk of increased spending speculative and declined to give details. The Detroit automaker is also expected to discuss a new timeline for many of the EVs to follow those already identified, such as the GMC Hummer EV pickup and Cadillac Lyriq crossover, people familiar with the plans said. Lyriq (shown above) is slated to go into production in late 2022, but GM officials have been stung by criticism the automaker was bringing the vehicle to market too late, one source said. "The pull-ahead in programs is real and the organization is really doubling down on speeding up product development," the source said. Barra and other GM executives have been signaling the automaker's EV acceleration plans. She said earlier this month GM would boost capital spending over the next three years to speed EV development and was talking with other automakers about partnerships to develop more vehicles using GM's battery technology. Last week, a GM executive said the company had pulled forward the rollout of two "major" EV programs, and GM officials have touted the faster 18-month development time for the Hummer truck. Tesla's soaring market capitalization, and growing pressure from regulators to phase out carbon-emitting engines, has put pressure on established automakers to respond to investors who view their internal combustion lineups as outmoded and doomed in the long run. A critical part of GM's pitch to investors has been its new Ultium batteries, which it estimates will offer an electric driving range of 400 miles or more on a single charge. It is building a battery plant with Korean battery maker LG Chem in northeast Ohio.

2020 Lincoln Corsair vs 2020 Cadillac XT4 | How they compare on paper

The 2020 Lincoln Corsair compact crossover was introduced this year to replace the aging MKC. Our first impressions are that it's a thoroughly competent luxury machine, but where it fits in the market is interesting. Given its size and price tag, the Corsair basically slots in-between compact segments, with vehicles like the Audi Q3 below and Audi Q5 above. It's a distinctive position to be in, but not a unique one, as there's another comparably sized and priced SUV -- and an American rival, no less. The Cadillac XT4 was launched just last year to be its company's smallest crossover, boasting compelling design and ample technology features.  So which is better? To give you some idea, let's take a look at each vehicle's horsepower, torque, fuel economy, space, pricing and some slightly more subjective aspects about their luxuriousness and feature sets. You'll find all the nitty gritty numbers below, followed by more detailed analysis. And if you'd like to compare other luxury crossovers, be sure to check out our comparison tool. Engines, drivetrains and driving impressions Both the Corsair and XT4 come standard with turbocharged 2.0-liter four-cylinder engines, but the Corsair's is more potent with 250 horsepower and 275 pound-feet compared with the 237 horsepower and 258 pound-feet of the Cadillac. And to seal the deal, the Corsair has an optional turbo 2.3-liter engine with 280 horsepower and 310 pound-feet of torque. That's not only vastly better than the Cadillac, but one of the most powerful outputs in the compact luxury SUV segment. Both vehicles have standard front-wheel drive with optional all-wheel drive on the base engines. The 2.3-liter Corsair has all-wheel drive standard. The Cadillac does boast an extra cog in its transmission over the Corsair's eight-speed automatic, but there's not necessarily an advantage or disadvantage to be gleaned from that. When it coes to fuel economy, the Cadillac is victorious with a 26 mpg combined rating for the front-drive model, with the front-drive 2.0-liter Corsair coming just behind with 25 mpg combined. It's a three-way tie for third with the all-wheel-drive XT4, all-wheel-drive 2.0-liter Corsair and 2.3-liter Corsair all returning 24 mpg combined. Of course, the all-wheel-drive Corsairs have a small advantage here in that it delivers more power and torque than the Cadillac with the same fuel economy.

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.
