Pure Vision Design TT Camaro has 1,400 reasons to want it

We've talked about Pure Vision Design before, a California-based company that made waves at last year's SEMA show with its Martini-liveried, Indy-car-powered Ford Mustang. That same car later starred in a Petrolicious video we showed you just a few weeks back. The company's latest creation is a menacing car it calls the Pure Vision Design TT Camaro. Based on a 1972 model, this car shares the Martini Mustang's clean styling and obsession with details.
Unlike the Mustang, which draws its power from a mid-60s Lotus-Ford Indycar engine, the "TT" in this Camaro's name implies something far more potent. The Nelson Racing Engines 427-cubic-inch V8 has been fitted with a pair of turbochargers, with a claimed output of 1,400 horsepower. That's almost 1,000 more than the Martini Mustang.
A six-speed Magnum transmission dispatches that power to the ground, while Pirelli PZero tires are tasked with (somehow) trying to grip the road. Baer brakes hide behind those HRE rims, while JRI coilovers and HyperTech springs bless the Camaro with some degree of competency in the bends.

Texas sues GM, saying it tricked customers into sharing driving data sold to insurers

Texas filed a lawsuit Tuesday against GM over years of alleged abuse of customers' data and trust. New car owners were presented with a "confusing and highly misleading" process that was implied to be for their safety, but "was no more than a deceptively designed sales flow" that surrendered their data for GM to sell. The suit contends that at no point was selling driving data ever even suggested as a possibility, putting GM in violation of the state's consumer protection laws. Texas Attorney General Ken Paxton is seeking a jury trial and at least $10,000 per offense (every GM car sold in the state since 2015) and a hefty add-on of $250,000 in cases where the victim was over 65. Texas seems to be flying high after a recent $1.4 billion settlement from Meta over other privacy concerns. This may well be a way to solve any pending budgetary issues in the Lone Star State.

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.
