2015 Chevy Tahoe gets Police Patrol Vehicle treatment

That was fast. Mere days after showing a Police Concept based on the 2015 Tahoe at the SEMA Show, Chevrolet has announced that it will build a PPV model based on the SUV to do battle with the Ford Police Interceptor Utility (Explorer) and Dodge Durango Special Service.
You'll recall that the Tahoe has been police staple for several years, predating both the Explorer and Durango police variants, so the fact that the new model would spawn a police variant is hardly surprising. Like the civilian model, the 2015 PPV benefits from a more efficient 5.3-liter, direct-injection V8 that pumps out 355 horsepower and 383 pound-feet of torque. It also features more high-strength steel, offering better crash protection, on top of optional safety items like lane departure warning, forward collision alert and a Safety Alert Seat.
The press release is rather light on police-specific items, aside from the auxiliary battery, which keeps the myriad of electronics in a modern police car running even when the engine isn't. Lightbars, 17-inch steel wheels on Goodyear Eagle RS-A tires and a push bar round out the mods for the Tahoe PPV. The cabin features a revised center console and room for laptop and other equipment mounts.

Callaway debuts its new C7 Stingray at National Corvette Museum

Callaway showed off its first tuned version of the 2014 Corvette Stingray at the National Corvette Museum last week, giving the rampant enthusiasts of America's sports car a look at the roughly 620-horsepower, supercharged rocket.
Unlike the Corvette SC610 we showed you back in January, this Stingray packs a fair bit more oomph. Horsepower is only up ten ponies, but torque has jumped from 556 pound-feet to "at least" 600 pound-feet. Neither horsepower nor torque is official quite yet, although Callaway is expecting to know just what its creation can do once testing and validation is completed later this month.
The 6.2-liter, supercharged V8 now boasts a new, three-element intercooler, which Callaway claims only allowed the inlet air temperature to increase by ten degrees Fahrenheit during dyno runs. Previous designs saw a 35-degree-Fahrenheit jump. The exhaust system has also been fettled with, and now is even less restrictive.

2014 Chevrolet Malibu gets more torque, more room and inspiration from the Impala

The 2014 Chevrolet Malibu, having stared at the Impala across the showroom floor for a year, gets nips and tucks all over inspired by its larger brother. The 2.5-liter four-cylinder in the base car will get a stop-start system and 23 city miles per gallon, 35 highway, each number representing a one-mpg improvement over the 2013 car. Output is 196 horsepower and 186 pound-feet of torque.
Opt for the 2.0-liter turbo and, while power holds steady at 259 hp, torque goes up by 14 percent to a striking 295 lb-ft (a figure Chevy calls best in the class). The final details include newly programmed transmission shift points and faster shifts, for better engaging and enjoying the added power.
Looks-wise, the grille's been reshaped to be more in line with the new Chevrolet look, a narrower upper grille hovering over a larger lower grille.
