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.

Since 2010, Chevy Volt has outsold Nissan Leaf by just two units

The first two plug-in vehicles from major automakers in the US were the Chevy Volt and the Nissan Leaf. Ever since they went on sale to much fanfare in late 2010, we've been tracking the monthly sales with great interest (and, of course, other green vehicle sales as well). After a big initial lead by the Volt – the Volt outsold the Leaf 23,461 to 9,819 in 2012 – the Leaf has been chugging along and outsold the Volt every month since November 2013. We knew that the cumulative totals would soon tip in favor of the Leaf, but for at least one more month, the Volt is going to be able to say its the most popular plug-in vehicle in the US. Overall, for all officially reported sales of the Leaf and the Volt, things are almost exactly tied. Since the vehicles went on sale in the end of 2010 until the end of February 2015, the Volt has sold 74,592 units and the Leaf has sold ... drumroll please ... 74,590 units. For February, Leaf sales totaled 1,198 units, a 17-percent drop from the 1,425 Leafs sold last February. Brendan Jones, Nissan's director of Electric Vehicle Sales and Infrastructure, said in a statement that, "Tough winter weather in several key markets held EV sales back in February. As we head into spring, we look forward to seeing more dealership traffic so shoppers can experience firsthand the benefits of the all-electric Nissan Leaf." Of course, it was cold in the US last February, too, but we're sure that the nasty weather did indeed play a role last month. Things were even worse for the Chevy Volt, which dropped to just 693 copies sold, down 47 percent from the 1,210 sold last year. That's just barely enough for Chevy to keep talking about its plug-in sales leadership, but we expect the message to change once the March numbers come out next month. Related Video:

Audi S4 drivers are the most accident-prone, insurance report says

Culling data from more than 4.6 million automobile insurance applications, researchers at the Insurify insurance comparison marketplace picked a winner — or more to the point, a loser — in its determination of the car model with the most accidents so far in 2023: the Audi S4. Why does the sporty, luxury-class German sedan rank so high (or so low)? The organization found that S4 drivers, piloting a car with almost 350 horsepower, are among those who collect the most speeding tickets, and that they get into accidents at a rate 54 percent higher than the national average. If the S4 isnÂ’t a surprise with an at-fault accident rate of 11.7 percent, consider the “family friendly” brand that appears three times on the Insurity list: Subaru. It is represented by three models, including the turbocharged WRX and XV Crosstrek, and at the better-performing bottom of the list, the Subaru Impreza, with an accident rate of 10.3 percent.  In 2023, 7.6 percent of U.S. drivers were involved in at least one at-fault accident in the prior seven years. For drivers of cars on this list, the average at-fault accident rate was 10.5 percent, meaning these drivers are 1.4 times as likely to have an at-fault accident on record. According to its statement, the Insurity data science team explored key safety features, driver behavior, and Insurance Institute for Highway Safety (IIHS) evaluations to pinpoint possible reasons behind these carsÂ’ high accident rates. Following is the list, counting down to the models with most reported accidents: 10. Subaru Impreza (percentage of drivers with a prior at-fault accident on record: 10.3 percent; MSRP base model): $19,795) 9. Kia Niro (percentage of drivers with a prior at-fault accident on record: 10.4 percent; MSRP base model): $26,590) 8. Chevrolet Silverado LD (percentage of drivers with a prior at-fault accident on record: 10.4%, MSRP base model): $34,500) 7. Subaru XV Crosstrek (percentage of drivers with a prior at-fault accident on record: 10.5 percent, MSRP 6. Subaru WRX.(percentage of drivers with a prior at-fault accident on record: 10.7% MSRP base model): $29,605) 5. Toyota GR86 (percentage of drivers with a prior at-fault accident on record: 10.8 percent MSRP base model): $29,900) 4. Hyundai Veloster N (percentage of drivers with a prior at-fault accident on record: 10.9 percent; MSRP base model): $32,500) 3.
