GT-R driver walks away from terrifying dragstrip accident

With all-wheel drive, launch control and a dual-clutch transmission, the Nissan GT-R may be easier to manage than most supercars. But that doesn't mean that dragging one on a wet strip is a good idea.
Filmed at the Unlimited 500+ drag race in Moscow, Russia, this video depicts a pair of GT-Rs going head to head. But things didn't go quite as planned when the driver of one lost control of her twin-turbo supercar. We'll let the video below speak for itself, but thankfully it appears no one was hurt - an outcome that seems particularly remarkable in light of the fact that it appears that the driver was not wearing a fire suit or helmet.

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 prices replacement Leaf battery at $5,500

The battery pack is the single most expensive component in a plug-in vehicle and, until now, figuring out the cost to replace one has been a bit of a mystery. Last year, Nissan tried a $100/month price for a new battery in its popular Leaf, but was loudly criticized for that attempt. Today, Nissan is changing gears with a big announcement regarding the price of a new pack for your Nissan Leaf: $5,500 to buy. With an asterisk. Nissan's Brian Brockman, writing at My Nissan Leaf, announced that Nissan Leaf replacement batteries are now available to purchase at certified Leaf dealers in the US at a suggested retail price of $5,499. These packs are the ones found in 2015 Leaf models, which are similar to the ones the Leaf has always had, just with a different, better battery chemistry. To buy a new pack, you need to give Nissan your original battery pack (which Nissan says will be recycled and has a value of $1,000) and the $5,500 "does not include tax, installation fees or an installation kit required for 2011 and 2012 vehicles." That kit costs around $225. A $100/month financing program will still be available (details will be made available later) but now it will have an end date and the driver will own the pack at the end of the payment process. All replacement packs will have the same eight-year, 100,000-mile warranty as the battery in a new Leaf. You can read Brockman's full statement below or over on My Nissan Leaf. Ever since the Leaf entered the market in late 2010, Nissan has been dealing with degrading battery issue, both as a real thing (in warm climates like Arizona) and as a worry in the mind of potential customers. Now that we know how much it'll cost to get a new pack, we can calculate that the overall cost for a new 24-kWh pack is now officially $6,500. That means the price to a customer is less than $270-per-kWh. That's quite low compared to some early estimates, right on target with others and a very big deal for EV shoppers and drivers out there. Hi all: I'm happy to be back to provide a long-awaited update on the Nissan LEAF battery replacement plan. Last year, I posted preliminary details of the program that we'd created based on early survey data, and it led to spirited discussion (and very vocal criticism). So we went back to the drawing board with your comments and the ongoing guidance of the LEAF Advisory Board.
