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.

Opel Ampera-e brings a Bolt of EV driving to Europe

The Chevrolet Bolt will take a trip across the Atlantic in 2017 to become Europe's Opel Ampera-e. General Motors won't release any specs for the foreign version yet, but these photos suggest very minor styling tweaks to the upper level of the grille and to the hatchback to add the appropriate brand emblems. We would expect the same electric motor with 200 horsepower and 266 pound-feet of torque and 60-kWh battery as the US model, too. However, the 200-mile range number might change, but only because of the differences in European testing. GM CEO Mary Barra announced the Ampera-e at the CAR Symposium in Bochum, Germany. "GM and Opel have always been convinced that electric cars will play a defining role in future mobility. The game-changing technology of the Ampera-e is a significant step toward realizing that vision," she said. The Ampera-e is also proof that General Motors loves confusing naming for its green models. If the Volt and Bolt aren't perplexing enough, the Ampera-e is just one letter off from the Ampera – the previous-gen Volt in Europe. GM no longer sells the range-extended vehicle there, so at least both names can't be in showrooms simultaneously. However, the similar monikers still might confuse some customers who think the new EV hatchback is closely related to the old sedan.

Opel Group will launch a revolutionary new battery electric car next year, as the company continues the biggest, most far-reaching model offensive in its history with 29 new models between 2016 and 2020. The new five-door, five seat will be called "Ampera-e". It will not only have a longer range on a full charge than most electric cars, it will also be affordably priced. Building on the electrification expertise established with the original Ampera, which set the benchmark for modern electric cars in 2011, the new Ampera-e combines innovative electric-mobility with state-of-the-art connectivity and exciting driving dynamics. Announcing the Ampera-e today at the CAR Symposium in Bochum, Germany, GM Chairman & CEO Mary Barra said: "GM and Opel have always been convinced that electric cars will play a defining role in future mobility.

GM resumes production of its 3.0-liter turbodiesel straight-six

General Motors temporarily stopped taking orders for trucks and SUVs equipped with the 3.0-liter Duramax turbodiesel six-cylinder engine in August 2021 due to a supplier shortage. Reports claimed the pause would last through 2021, but the engine is already back in production. Enthusiast website GM Authority learned from sources inside General Motors that the straight-six is once again coming off the assembly line at the Flint Engine Plant in Flint, Michigan. There's no official word on precisely what the problem was linked to and whether it was related to the on-going chip shortage that's wreaking havoc across the automotive industry. All we know is that the pause lasted for about two weeks. Called LM2 internally, the six is available in Chevrolet's Tahoe, Suburban, and Silverado 1500 and in GMC's version of these trucks. It's also an option in the Cadillac Escalade. It develops 277 horsepower at 3,750 rpm and a V8-like 460 pound-feet of torque at 1,500 rpm in every application, and it allows these big behemoths to post surprising fuel economy numbers. Fitted to a rear-wheel-drive Tahoe, the Duramax returns 21 mpg in the city, 28 mpg on the highway, and 24 mpg in a combined cycle, figures that make it more efficient than a Blazer. Demand for the diesel-powered trucks is relatively high. While the shortage undoubtedly took a toll on sales, the Duramax represented 8% of Suburban sales and 6% of Tahoe sales in May 2021. There are no other diesel-burning full-size SUVs available new so they have the market to themselves. On the truck side, Ram still makes the EcoDiesel available on some 1500 trims but Ford abandoned the segment.
