Nissan Leaf sales double Chevy Volt to close out winning 2014

To close out the year, sales of the two most-popular plug-in vehicles in the US kept going in the direction that they had been all year. The Chevy Volt dropped and the Nissan Leaf had another record month. Sound familiar? The Volt sold 1,490 units in December, a year-to-year drop of 37.7 percent. For all of 2014, Volt sales were down 18.6 percent to just 18,805 (from 23,094 in 2013). On the Nissan side of the ledger, the Leaf sold 3,102 units, up 22.7 percent from the 2,529 sold in December 2013. For the year, Nissan sold 30,200 Leafs, up 33.6 percent from the 22,610 sold in 2013. A few other things to note: For every month in 2014, the Leaf sold more than it did for the same month in 2013. For the Volt, this was only true for three months (April, May and July). Funnily enough, the Volt sold exactly 1,478 units in both March 2013 and 2014. The Volt's 2014 total was lower than both 2013 and 2012, while the Leaf had its best year ever. There were three months in 2014 when people bought at least twice as many Leafs than bought a Volt (September, November, December). The Leaf outsold the Volt every month in 2014. The closest gap was 215 units, in February. The biggest was 1,612, in December. As you've most likely seen, GM is still busy teasing the new Volt, which will make its official debut at the Detroit Auto Show next week. We'll have a more in-depth green car sales post up soon. <iframe embedded="true" "="" scrolling="no" src="https://docs.google.com/spreadsheets/d/1oIuH75vaSHaaplD4x6gLsYjSsiN4oGmez1T63eaYdhY/pubhtml?widget=true&headers=false" height="430"> Nissan celebrates 30,000 leaf sales in 2014, best year ever for sales of any plug-in vehicle NASHVILLE, Tenn. (Jan. 5, 2015) – Nissan, the world leader in electric vehicle sales, shattered yet another sales record with 30,200 LEAF vehicles sold in 2014, which is the first time any plug-in has sold more than 30,000 units in a single year. "Now in its fifth model year, Nissan LEAF is more popular than ever and continues to bring new buyers to Nissan," said Brendan Jones, director, Nissan Electric Vehicle Sales and Infrastructure. "From the beginning our vision was to bring electric vehicles to the mass market in a practical and fun-to-drive package, which is what makes Nissan LEAF the best-selling electric car in the world." Last month, Nissan sold 3,102 all-electric LEAFs, up 22.7 percent from the prior year and a December record.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.

Junkyard Gem: 1988 Chevrolet Spectrum Sport Coupe

Before General Motors created the Geo brand for cars built or designed by its overseas partners, the Chevrolet Division put its badges on U.S.-market versions of the Toyota Corolla Sprinter, the Suzuki Cultus and the Isuzu Gemini. Those cars were known as the Nova, the Sprint and the Spectrum, and all became Geos starting with the 1989 model year. Today's Junkyard Gem is one of the last Chevy Spectrums ever sold, found in a Denver self-service yard a few months ago. Midway through 1988, the Chevrolet Spectrum abruptly became the Geo Spectrum and was assigned to the 1989 model year. This car was built in May 1988, making it one of the very last of the pre-Geo Spectrums. The Chevrolet/Geo Spectrum was available as a four-door sedan and as a three-door hatchback, from the 1985 through 1989 model years. For 1988 only, a Spectrum Sport Coupe package, featuring some trim upgrades and these rad decals, could be had on the hatchback. This car was essentially identical to its Isuzu-badged counterpart, the I-Mark. In 1988, the MSRP for the cheapest possible Chevy Spectrum hatchback (the stripped-down Spectrum Express) was $6,495, while its somewhat better-equipped I-Mark twin started at $7,439 (that's $17,128 and $19,617 in 2023 dollars). Meanwhile, the base Hyundai Excel hatchback listed at $5,295 and the Yugo GV cost a hilarious $4,199 ($13,963 and $10,941 in today's money). Power came from this 1.5-liter SOHC four-cylinder, rated at 70 horsepower. A turbocharged version with 110 horsepower was available as well. You could get an automatic transmission in the Spectrum, but this car has the base five-speed manual. This car didn't get the optional air conditioning, but at least it has the traditional Isuzu HVAC control icons featuring blow-dried hair and high-heeled dominatrix boots. Just over 170,000 miles on the odometer. Someone installed a pretty good (for the 1980s) Blaupunkt Charlotte CR148 cassette deck in the dash. This was a necessity if you wanted to enjoy full appreciation of the music of the era. The Spectrum is special! It's as slick as city rain. "I didn't spend a lot of money but with my Spectrum it looks like I did." Joe Isuzu mocked Toyota salesmen when pitching the I-Mark. As was nearly always the case during the 1980s, the JDM ads for the same car were much more fun. They should have recreated this commercial with Spectrums.
