GM says over 40% of new China launches in next five years will be EVs

SHANGHAI — General Motors is planning an electric car offensive in China with more than 40% of its new launches in the country over the next five years set to be electric vehicles (EVs), the U.S. carmaker said on Wednesday. GM's electric vehicles, many of which will be all-electric battery cars, will be manufactured in China with almost all parts coming from local suppliers, the company said in a statement released at its Tech Day event in Shanghai. Reuters reported earlier on Wednesday that GM was planning to overhaul its Chinese line-up to stem a slide of sales after more than two decades of growth in a country that contributes nearly a fifth of its profit. GM's new China boss Julian Blissett told Reuters that new technologies, such as EVs and cars with near hands-free driving for highways, would play a key role in GM's China initiatives, which are part of a push to get annual sales in the country back to the 4 million peak it hit in 2017. GM did not say in its statement how many new or significantly redesigned models it was planning to launch in China over the next five years. "China will play a crucial role in making our vision a reality," GM CEO Mary Barra said in the statement, referring to its initiative to create what it describes as a future of "zero crashes, zero emissions and zero congestion" through electrification and smart-driving technologies. GM has said it plans to invest more than $20 billion in electric and automated vehicles globally by 2025. It was not clear how much of that investment will be spent in China.

2014 Chevrolet SS makes its live debut

Chevrolet showed off the new 2014 SS in an airport hangar last night, its first rear-wheel-drive performance sedan in the US since the Impala SS from 1997. We'll have more to say about the SS later today, but this is the sedan that Chevrolet sees as the final piece in restoring its performance credentials. For those of you looking for a manual transmission, however, that wish will go unfulfilled - at least for now: the only two options buyers will have are the color and whether or not they want a sunroof.
We'll work on getting some more angles (in better light) today at Daytona International Speedway, but with fans seeing the car for the first time, we don't hold out much luck of getting a clear shot. So for now, enjoy the high-res gallery above.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).
