New Chevy Small Block crate engine has 405 hp, endless possibilities

With decades of history, the Chevrolet Small Block V8 has definitely stood the test of time, and the company has kept finding ways to make it better. At this year's SEMA Show in November, Chevy Performance is unveiling the latest upgrade to that legacy with the new ZZ6 350-cubic-inch (5.7-liter) crate engine. Offering 405 horsepower and 405 pound-feet of torque, the mill should add a big dose of power to any project car. For the ZZ6, Chevy is working to improve the Small Block's high-rpm performance. To make that happen, the engine has Fast Burn aluminum cylinder heads and an updated valvetrain inspired by the LS family of powerplants. Large intake runners help with the airflow, and the valve springs use a tapered design that allows for less reciprocating mass. The mill also packs a forged steel crankshaft and high-silicon aluminum pistons inside of a cast iron block. Chevy is offering the engine in two versions depending on what the builder needs. The Base configuration comes with an intake, distributor, water pump, and a few other parts but lacks carburetor and accessories. Conversely, the Turn Key option has everything, including the carb, air cleaner, starter, alternator, and more. More details about their availability will be announced at SEMA. NEW ZZ6 CHEVY SMALL BLOCK ADVANCES CRATE ENGINE LEGACY Revised Fast Burn heads with LS-inspired valvetrain enhance high-rpm performance 2015-10-02 DETROIT – Developed with contemporary technologies, including a high-rpm valvetrain, Chevrolet Performance's new ZZ6 crate engine offers builders a modern twist on the classic Chevy Small Block 350. It uses updated Fast Burn cylinder heads with beehive-style valve springs inspired by the LS engine family – a feature that enhances high-rpm capability, enabling the new high-performance engine to achieve 405 horsepower and 405 lb-ft of torque. That's more power than any factory produced 350 engine ever installed in a Chevrolet production vehicle and it's one of the most powerful 350 Small Block-based crate engines in the nearly 27-year history of the "ZZ" lineup. "The new ZZ6 is the ultimate ZZ 350-based crate engine from Chevrolet Performance," said Jim Campbell, GM U.S. vice president of Performance Vehicles and Motorsports.

GM delaying additional Silverado EV and Sierra EV production to Q4 2025

This looks like more "Gotcha!" news about storms in the EV sector, but the word "additional" is key here. The Detroit News reported today that GM is pushing delaying production of the Chevrolet Silverado EV and GMC Sierra EV pickups at the Orion Assembly Plant to late 2025, about a year behind expectations. The Silverado EV Work Truck is already in production at GM's Factory Zero in Detroit, which won't change. Retail versions of the Silverado EV are still planned for production at Factory Zero before the end of this year, and the Sierra EV is expected to enter production at Factory Zero early next year. This new plan simply means GM won't add more production of those electric trucks at Orion.  GM builds the Chevrolet Bolt at Orion right now, assembly of that groundbreaking car to end this year. GM's original idea was to spend $4 billion to convert Orion to EV pickup production in time to get its two giant profit makers rolling down lines in early 2025. The move to late 2025 could mean the plant is out of commission for about two years. The facility's 1,261 employees are being offered spots in other plants, including Factory Zero.  The automaker gave several reasons for the move, a spokesperson telling The Detroit News the company wants "to better manage capital investment while aligning with evolving EV demand," and telling the Detroit Free Press, "We're looking at EV demand and the trendline for EVs is stabilizing. ... It is not rising as fast as originally forecasted." On top of that, engineers "have identified engineering improvements that we will implement to increase the profitability of our products." The spokesperson also made it clear that the delay has nothing to do with the UAW strike, now in its 32nd day.  Factory Zero's working up to a near-term production capacity of about 600,000 units annually, GM saying it wanted to get capacity to 1 million EVs annually by the end of 2025. At the moment, the site builds the Silverado EV Work Truck, the GMC Hummer EV pickup and SUV, and the Cruise Origin shuttles — not the Bolt taxis, the autonomous pods. The Detroit News reported GM sold 18 Silverado EV Work Trucks in Q3 this year, GM Authority says GMC Hummer EV production has ramped up to about 3,000 units per month, and Cruise Origin is still waiting on approval from the National Highway Safety Traffic Administration to mass-produce the autonomous shuttles because the shuttles need an exemption for not having steering wheels.

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.
