Cadillac Lyriq teased ahead of debut next week

The Cadillac Lyriq is just around the corner, set to be fully revealed on August 6. Cadillac just released a few teaser photos and videos as preparation for the big debut a week from today. It’s our best look at the production version of the car yet. Of course, you may remember photos of the EV concept released over a year ago, but the production crossover is shaping up to be a little different. This carÂ’s most intriguing element so far is the charge outlet panel integrated into the front fender. The large piece appears to lift up and slide out of the way when itÂ’s time to plug in. This reveals a decorative LED light strip that outlines the outlet, ultimately leading into the Cadillac logo above. Below the panel is a small, silver GM badge that if our guess is correct, says “Ultium” for the Ultium battery technology going into the Lyriq.  The wheels feature a unique silver and black two-tone design. Those black inserts are ridged, and the wheel is likely designed for better aero performance and increased range. ItÂ’s tough to say much about the design itself, but the silhouette is giving us crossover coupe vibes with its heavily raked rear window and sloping roofline. It appears to have a couple spoilers, one on the roof and then another as a ducktail below the rear window. CadillacÂ’s video teasers provide for the briefest of front end glimpses. Still, we can see the fancy lighting signature that Cadillac has created. ThereÂ’s both a light-up Cadillac badge and small LED lighting strips integrated throughout the grille. ItÂ’s concept car-like in appearance, so we do wonder whether this will find its way into a production Lyriq. The vertical DRL weÂ’re used to seeing on other Cadillacs has also made an appearance on the outer edges of the front bumper. ItÂ’s been previously stated that the Lyriq would enter production in 2022, so even when GM does reveal the electric Cadillac next week, itÂ’ll be a long while till we see the vehicle on the road.

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.

Cadillac's striking Escala concept is reportedly headed for production

Cadillac is reportedly planning a new flagship four-door, and it won't be based on its alphanumeric naming system a la the CT6. It'll be the Escala, the stunning concept fastback it revealed in 2016 in Pebble Beach. The news comes via Autoline, which cites AutoForecast Solutions. The Escala is said to be planned for production starting in December 2021 at GM's Detroit-Hamtramck plant, which currently builds the CT6, Buick LaCrosse and Chevrolet Volt and Impala. That suggests the Escala, which was branded as a four-door coupe, will likely keep that layout. It'll also be built on the CT6 platform. Cadillac has been talking about fitting a flagship sedan above the CT6 for years, and the Escala's design language has been influencing bits of other Cadillac models, from the refresh of the CT6 to the broad grille shape on the new XT4 crossover, which debuts at the New York Auto Show next week. The concept Escala featured a wide, muscular stance and a minimalist, white mid-century modern interior aesthetic, with tail lamps that evoke waterfowl in flight. Interestingly, it came equipped with a 4.2-liter twin-turbo V8 with cylinder deactivation, which Cadillac President Johan De Nysschen said at the time was "absolutely worthy of a car of this caliber." But with such a long horizon before production, there's obviously lots of time to develop a more pragmatic production model and cue ravenous speculation. Or, for that matter, to decide to rename it something like the CT8.
