This dream home theater and office happens to be in a Cadillac Escalade [w/video]

Need to take a ride cross country in the lap of luxury while still getting some work done? Short of a tour bus, the Concept One Curve from Lexani Motorcars might be one of the most comfy options imaginable. Lexani is usually known for creating opulent armored vehicles, but for the Concept One Curve it focuses on converting a 2015 Cadillac Escalade into a place for work or play. The company strips out the standard passenger compartment to install a higher ceiling with LED lighting, two leather-upholstered power captain's chairs and jump seats. However, the real highlight is a 48-inch curved 4K television mounted against the driver's partition. Don't worry about missing your favorite shows because there's a TracVision Satellite, too. The driver gets a re-covered seat of their own up front. If business needs to get done, the vehicle also includes a Mac Mini computer, tables stowed in the seats and connections for video conferencing. Of course, if you're riding in something this lavish, security might be a concern too. In addition to the window shades, the Concept One Curve features cameras to know what's going on outside. A touchscreen management system lets occupants control the whole setup from the luxurious chairs. Lexani claims that if all of this somehow isn't enough for a buyer, it offers even more options to fit their needs. Scroll down to watch a video tour and read more about this rolling home theater. {C} Lexani Concept One Curve Lexani Motorcars, a boutique luxury conversion company receiving vast international praise, has produced the Concept One Curve - the world's first 2015 Escalade with a built-in 48" 4K Technology Curved Smart TV. Lexani Motorcars is constantly pushing the boundaries of possibility for luxury transportation in everyday vehicles. The Curve is a revisited version of their latest model, the Concept One, with a television upgrade and electronic rear curtains; it is unmatched in its ability to be a premier theater one minute and a five-star mobile office the next. The curved smart TV-which rests on a proprietary electronic partition-is indeed impressive, but it is just one of the numerous amenities this discreet masterpiece boasts.

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.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.
