Cadillac Elmiraj Concept slinks in Leno's Garage

Jay Leno's Garage has moved to Pebble Beach for the week. This time around, the affable comedian is taking a look at the Cadillac Elmiraj Concept that debuted during the Monterey car week, and is talking to General Motors vice president of global design, Ed Welburn.
There's plenty of reminiscing about what concept cars were like when these two were kids, before a fairly deep dive into the striking Elmiraj Concept itself. Welburn shares a few anecdotes about the design process behind the two-door concept, including how his designers changed his mind on the grille design.
After bringing up the Cimarron, Leno makes a solid point that the Elmiraj would be a solid production car that could even spawn a four-door variant. We couldn't agree more. Take a look below for the full video from Jay Leno's Garage.

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.

Lyft and Ghostbusters want to take you for a ride in Ecto 1

Part of the fun of using a service like Lyft is that you never know exactly what kind of car will pick you up. And if you're in select cities this weekend, it could be the Ghostbusters' Ecto 1. Lyft is picking riders up in a 1982 Cadillac DeVille wagon decked out in the livery of everyone's favorite ghost catchers as part of a promotional tie-in with the new Ghostbusters movie. Just select Ghost Mode when ordering a car, and a decked-out Ecto 1 should appear. Customers can't ride with Slimer, but Lyft is packing each car with Hi-C Ecto Cooler – the relaunched juice drink that most older millennials lived on during their childhood – and Twinkies. If you're questioning the Twinkies, we strongly recommend you go back and watch the 1984 original. Egon will educate you. Riders in New York, Los Angeles, San Francisco, Boston, and Washington can order a free ride in Ecto 1 on Friday, July 1 or Saturday, July 2, between 10 a.m. and 6 p.m. Ghostbusters, starring Kristen Wiig, Melissa McCarthy, Leslie Jones, and Kate McKinnon, hits theaters on July 15.
