Is the Chevy Camaro Z/28 a Godzilla Slayer at the track?

Godzilla. It's a name that strikes fear in the minds and hearts of giant monsters (Mothra!) worldwide, not to mention a number of automobile manufacturers that produce high-performance coupes... including Chevrolet. The Bowtie-cladded company has one rather obvious model that lines up squarely in the sights of the Nissan GT-R, that being the Corvette.
Interestingly, though, Chevy's halo coupe isn't the vehicle the boys from Motor Trend decided to match up at Barber Motorsports Park against the Japanese Godzilla, opting instead for the brand-new Camaro Z/28. A glance at the spec sheet of the Z/28 clears up any consternation regarding MT's choice - more horsepower for the Nissan, more torque for the Chevy and roughly the same weight means they are on pretty equal ground when it comes to what's under the hood.
The rest of the spec sheet looks to tilt the argument in the GT-R's favor (especially considering that MT's test car is a Track Edition model), as it boasts all-wheel-drive traction, a quick-shifting six-speed dual-clutch transmission and a price tag that's about $40,000 higher than that of the Z/28. Oh, and don't forget the GT-R's legendary computer-controlled reflexes. Does any of that matter with a professional race car driver like Randy Pobst behind the wheel? Scroll down and watch the video to find out.

A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

Nissan Leaf makes it 19 in a row for record sales; Chevy Volt drops 21 percent

The Nissan Leaf continues its streak of "best month ever" sales with 2,881 EVs sold in September. Compared to the 1,953 sold in September 2013, that represents an increase of 47.5 percent and, as Nissan itself must be tired of saying by now, it marks yet another best month ever, same as last month and now the 19th in a row. Okay, sure, we know, Nissan will tout this run for as long as it can, but we're certainly expecting it each month, so if it ever doesn't happen, it'll be interesting to see how Nissan talks about it. Year-to-date, Leaf sales are up 35.7 percent compared to 2013. In any case, Nissan's director of EV marketing, Toby Perry, sent AutoblogGreen a statement that said, "Nissan Leaf owners have turned into some of our best marketers, and they jump at any opportunity to share their enthusiasm with friends and family. Take National Drive Electric Week – a grassroots celebration of all things EV and the perfect platform for LEAF owners to showcase the benefits of going electric. After celebrating with EV owners in more than 130 cities across the country, we saw a significant increase in Leaf showroom visits with midweek traffic just as heavy as what we see on the weekends." Year-to-date, Leaf sales are up 35.7 percent compared to 2013. Over on the Chevy Volt front, things aren't quite as rosy. After coming off a good August (the best sales month of 2014 by almost 500 units), Volt sales were down to 1,394, a decrease of 21.1 percent compared to September 2013. So far this year, Volt sales are down 13.2 percent year-over-year. It's kind of a stretch, but perhaps people are already waiting for the next-gen Volt, which will be revealed at the Detroit Auto Show in January, to go on sale? Speaking of things we say every month, our in-depth round-up of US green car sales is in process and will be appearing soon.
