2015 Callaway Corvette Z06 gets new supercharger, adds $17K to starting price

Callaway's proud tradition of modifying Chevrolets is about to add a very significant chapter this weekend, as the company prepares to unveil a modified version of the 2015 Corvette Z06. The engine mods are simple, though we expect them to be very potent. That's because Chevy has replaced the factory supercharger with a new "GenThree" unit that's nearly a third larger than what's bolted on in Bowling Green. A new intercooler is also added, along with a new high-flow intake system. Beyond that, the changes are exclusively of the subtle cosmetic variety. There's new badging inside and out, as well as new engine covers, floormats and an underhood plaque. Naturally, there's documentation to verify the Callaway Z06's authenticity, and the comfort that comes with a three-year, 36,000-mile warranty. Callaway has priced the upgrade package at $16,995, in addition to the price of the stock Z06. While we're still waiting to hear official power figures, that seems like a reasonable asking price for what were wagering will be a major increase in power. The Callaway Z06 will debut this weekend at the National Corvette Museum's C7 Bash in Bowling Green, KY. Expect more details following the debut. Scroll down for the official press release.

Here's a sneak peek at the new package. Based on Chevrolet's track-proven Z06, Callaway engineers' no-compromise approach takes this Corvette to an astounding power level. While advertised Callaway horsepower and torque are pending final validation, the Callaway package adds Callaway's new GenThree supercharger system with 32% more displacement than the stock Z06 supercharger, improved manifold design and unique triple-element intercooling system. Callaway engineers recognize that a key contributor to maximizing power is reduction of inlet air temperature. By exposing the supercharger's large plenum area to outside ambient airflow, the design takes advantage of the significant charge air temperature reduction provided by convective cooling. The completely redesigned intercooling system also helps maintain nearly ambient charge air temperature with exceptionally low air restriction.

GM trucks get hybrid versions, but you'll probably never see one

A few years ago, General Motors sold hybrid versions of its Chevy Silverado and GMC Sierra pickups. They weren't very good, using GM's old two-mode hybrid system that resulted in only negligible fuel economy gains. But GM's trying again, launching eAssist models of the 2016 Silverado and Sierra that are said to offer 2-mpg improvements in city, highway, and combined fuel economy ratings. Problem is, you probably won't be able to get one. Only 700 eAssist trucks will be made for the 2016 model year – 500 Silverados and 200 Sierras. When you consider that GM moved 824,683 examples of its light-duty pickups in 2015, this small run represents 0.08-percent of all Silverado/Sierra production, and GM says it "will monitor the market closely ... and adjust as appropriate moving forward." But that's not the only limitation. The eAssist trucks will only be sold through California dealers. For the Silverado, eAssist can only be optioned on the 1500 Crew Cab 1LT 2WD model, and for the Sierra, the fuel-saving technology is solely available on the 1500 SLT Crew Cab 2WD model with the SLT Premium Plus package. Granted, in terms of the Sierra, that means you get niceties like LED headlights and taillights, Apple CarPlay and Android Auto, Bose premium audio, heated seats and steering wheel, lane keep assist, and more. In the trucks, eAssist combines a small electric motor and 0.45-kWh battery pack with the pickups' 5.3-liter V8. GM estimates total output of 355 horsepower and 383 pound-feet of torque – no more horsepower than the non-eAssist trucks, but three more pound-feet of torque. GM says the eAssist trucks can tow up to 9,400 pounds, and the battery only adds 100 pounds to the trucks' weight. The electric motor provides 13 hp and 44 lb-ft of torque for a boost of acceleration off the line, or during passing. It also allows the engine to run in four-cylinder mode for longer periods of time. eAssist uses regenerative braking to help power onboard electrical systems, and adds start/stop to the powertrain. Finally, the so-equipped trucks have a six-percent improvement in aerodynamics, thanks to a soft tonneau cover and active grille shutters in the front fascia. Great news is, the eAssist option is relatively inexpensive, only costing $500. But good luck getting your hands on one.

New Chevy Malibu helps parents monitor teen driver's performance

For teens, a driver's license can represent freedom. For parents, it can represent fear. Now there's a way parents can alleviate some of their worries and monitor their teen drivers. The 2016 Chevy Malibu, which debuted Wednesday at the New York Auto Show, contains a new feature that tracks driving performance and helps inexperienced drivers rein in some of their more dangerous habits. Accessed through a password in the car's infotainment system, parents can learn how far their child has driven, how fast they've gone and how many times they've braked hard, among other features. "It's an in-vehicle report card that gives parents information," says Mary Ann Beebe, one of the lead engineers who designed the system. "It's meant to be used as a teaching tool. Parents can sit down and talk with their teen about, 'Here are some areas where you're doing well, and here's some where you can use improvement.'" Car accidents are the leading cause of death for teens ages 16 to 19, and only last week, AAA released a study that found their driving behavior can leave them particularly susceptible to crashes. General Motors had sought ways to help educate and train younger drivers. In an era where data can be harvested from cars, monitoring performance is one way to provide information. Parents access the Teen Driver system in the car through a PIN-number entered into the Malibu's infotainment system. The report card can only be seen in the car – so far, it's not available via a smartphone app, like some other types of on-board diagnostic information. The system is activated by the use of a specially programmed key fob that lets the system know who is driving the car. Once the vehicle recognizes the key fob, it takes preventive measures to ensure safer conduct behind the wheel: Until the driver and front passenger buckle their seat belts, the radio is muted. Safety systems such as forward-collision assist and electronic stability control are automatically turned on. Parents can preset preferred speed limits, and drivers will hear a warning if that sound is exceeded. "We have these great technologies, and we want to make sure we turn them on for the teen," Beebe said. There are no geo-location aspects of the program, and data is stored on the car, not uploaded to the Cloud or even seen by General Motors, she said.
