Callaway, Lingenfelter boost Corvette Z06 way beyond 700 hp

With 650 horsepower and just as much torque on tap, few would accuse the latest Corvette Z06 of being down on power. But for those who'll always demand more, two leading Corvette tuners have just announced new tuning packages for the Z06 to boost Chevy's flagship well beyond 700 horsepower. The more powerful of the two comes from Callaway Cars, which has added a larger supercharger, a triple-action intercooler, and more to increase output to a massive 757 horsepower and 777 pound-feet of torque. The result, according to Callaway, is a 0-60 time quoted at 2.8 seconds and a quarter-mile run in 10.5. The package also includes a reshaped hood, all manner of trim upgrades, and a three-year warranty, and will set you back nearly $17k on top of the cost of donor vehicle that currently lists for $79,000. In what could only come second relative to Callaway's kit, Lingenfelter Performance Engineering has also released a Stage 1 package for the Z06. The kit includes a new dry sump damper, upgraded supercharger pulley and drive belt, and more – all of which Lingenfelter says will boost the Vette's output up to 720 hp and 730 lb-ft. Revised performance figures weren't released, but despite the 37-horse, 47 lb-ft deficit, we doubt it'd trail Callaway's by much. But both would likely leave the stock Z06 in their dust, and you can read more about them in the press releases below.

Equipped with Callaway's GenThree Supercharger, the Corvette Z06 now produces 757 bhp @ 6,200 rpm and 777 lb-ft @ 4,500 rpm (SAE). A launch to 60 mph is now achieved in 2.8 seconds, and a quarter-mile in 10.5 seconds at 131 mph. Why Go Big, When You Can Go Bigger? - Size Matters. To reach that power (which is up from 650 bhp / 650 lb-ft) the supercharger itself needed to be bigger since the output of a positive displacement supercharger is proportionate to its size. The Callaway GenThree supercharger is 32% larger in displacement (2300cc vs 1740cc). Cooling - Callaway engineers recognize that a key contributor to maximizing power is reduction of inlet air temperature associated with forced induction.

2016 Chevy Malibu exhaustively tested with four decades of data

Chevy is preparing to unveil its new Malibu sedan at the upcoming New York Auto Show next month. But when it does, it's not like it will have appeared overnight. The development of any new vehicle – especially one as widely produced by a major automaker as the Malibu – involves rigorous and relentlessly punishing tests. In the Malibu's case, that meant 1.5 million miles of driving from the scorching heat of Arizona in July to the frigid cold of northern Canada in January and everything in between. The Bowtie brand also says it incorporated four decades' worth of data taken from vehicles driving in locations around the world since 1972 in order to make the Malibu the best it could be. We'll have to wait to find out the results of all that exhaustive testing, but you can catch a sneak peek at the new sedan in the video above. Four Decades of Data Used to Test 2016 Chevrolet Malibu Recorded customer use drives durability testing for next-generation midsize sedan 2015-03-11 DETROIT – Data collected over decades from across the globe is helping ensure the 2016 Chevrolet Malibu can handle the world's worst roads even if the all-new midsize sedan never drives on them. Data collection boxes are placed in cars in real-world driving conditions around the world. Since 1972, these devices have accurately recorded the harshness and frequency of every jounce, bump and shudder inflicted on the car on roads in the U.S., Russia, Saudi Arabia and developing markets. "Although most Malibu owners will never put their car through similar abuse, we test all new vehicles in extreme climates, inclement weather and on punishing road surfaces," said Dan Devine, Malibu validation engineer. "The 2016 Malibu is definitely up to these challenges." Tests like these ensured the current generation Malibu was dependable and durable, two qualities that in turn helped Malibu stand out from its rivals in important quality surveys, such as J.D. Power's Initial Quality Study and Vehicle Dependability Study. General Motors engineers analyze the data to calculate the precise amount of damage potholes and other hazards create over 150,000 miles. Then the conditions are replicated at GM's Milford Proving Ground in Michigan on three unique road courses, each riddled with simulated potholes of increasing severity. Engineers run preproduction cars through the course up to hundreds of times.

Chevy Spark EV will go on sale in Maryland

The single-charge range of a Chevrolet Spark electric vehicle may not blow away anyone who's used to driving on a topped off tank of gas. But a full charge will actually get a Spark EV about halfway across the state of Maryland. Which is good because that state will be the first on the East Coast to sell the battery-electric model. General Motors said this week that Chevy Spark EV sales will start in Maryland this spring, and that federal and Maryland tax credits will get the out-of-pocket price of the Spark EV below the $18,000 threshold. GM took the opportunity to tout the Spark EV's 119 miles per gallon equivalent rating and says Maryland has sufficient charging infrastructure for drivers to welcome the EV without too much trouble. Last June, Spark EV distribution was reported to be ready to extend beyond the Pacific Coast. Specifically, Ohio was thought to be next in line to get Spark electric vehicles after four state car dealerships listed the model on their websites. GM's Randy Fox, however, quashed that real quick, saying only California and Oregon had sufficient infrastructure to support the Spark EV. GM first announced the Spark EV for public (or at least American) consumption back in 2011. Last year, the General sold 1,145 Spark EVs, up 87 percent from 2013. For more on the Maryland expansion, take a look at GM's press release below. Chevrolet Spark EV Plugs into Maryland Customer demand drives addition of East Coast; features locally sourced drive unit 2015-01-22 WASHINGTON, D.C. – Chevrolet will start selling the Spark EV in Maryland this spring, expanding the pure electric mini-car's "range" to the East Coast. The Spark EV is the most efficient U.S. retail electric vehicle on the market, delivering an EPA-estimated combined city/highway 119 MPGe fuel economy equivalent and 82 miles of EPA-estimated combined city/highway range. It is priced as low as $17,845, after federal and Maryland tax credits – and it features a locally sourced electric motor and drive unit, manufactured at General Motors' Baltimore Operations facility in White Marsh, Md. "The Spark EV has been one of the most well-received electric vehicles in the industry and customer demand helped make the decision to expand its availability to Maryland," said Steve Majoros, Chevrolet director of car marketing.
