GM will likely build PHEV batteries in China soon

It's a big week for batteries. Friday, Tesla will hold a big event at its Gigafactory in Reno, NV. But even in Michigan, there are things happening on the electrified automotive front. This was proven when GM invited journalists to its Brownstown Battery Assembly Plant today, highlighting the six different battery packs it makes for nine vehicles around the world (plus a tenth, coming to Asia, that has not yet been announced). During our tour, we learned a few interesting tidbits that we thought readers would like to hear: The Cadillac CT6 plug-in hybrid launches in China this fall before coming to the US next year. GM builds the battery packs in Michigan and ships them to China for final assembly in the PHEV. For now, this is all fine for GM to qualify for China's incentives for building green cars in the country. But, as Bill Wallace, GM's director of global battery systems, told AutoblogGreen, this could change thanks to the country's 'Made in China 2025' plan. The situation is "evolving," he said, and it's a safe assumption that GM will need to build packs in China some day. For the CT6 PHEVs that will be sold in the US, the batteries will make a round trip, since GM will only build the plug-in version in China. As for the range of the CT6 PHEV, that hasn't been announced, but since China offers incentives for vehicles that get at least 50 kilometers (31 miles), that's a likely target (the US range (UPDATE: GM did announce an expected range for the CT6 PHEV in the US at the LA Auto Show last fall, saying it would "travel approximately 30 miles on a full electric charge"). The battery pack in the CT6 is also a clunky box-type thing, totally unlike the near-elegant T-shape used in the Volt. This despite the fact that the guts of the two packs are similar. Both have 192 li-ion cells and weigh almost the same, but GM tuned the CT6 pack for acceleration instead of range, the way it did with the Volt's pack. Still, the main reason the packs are different is because the CT6 is a rear-wheel drive vehicle, and the tunnel that the Volt's pack uses is occupied by the driveshaft. Despite the highly touted second-gen Chevy Volt going on sale last year, GM still has the capacity to build battery packs for the old, first-gen model. This is because the company is legally required to be able to provide replacement packs for warrantied vehicles (for up to 10 years), and the second-gen packs don't fit into the first-gen vehicles.

2016 Cadillac CTS-V arrives with 640 hp, 200-mph top speed

Ask the company's executive team, and they'll tell you "this is the maximum Cadillac V-Series." It's the 2016 CTS-V sedan, and it packs the very best of what's possible at Cadillac. And the company says it doesn't think "anyone thought it was possible that we could push [the CTS-V] this far." The big news is what's underhood: General Motors' supercharged, 6.2-liter LT4 V8, tuned to 640 horsepower and 630 pound-feet of torque. That's 10 hp and 20 lb-ft less than the monstrous Corvette Z06, and the result is the most powerful car Cadillac has ever produced. With rear-wheel drive, launch control and the eight-speed automatic transmission (sorry, folks – no more manual transmission here), Cadillac says the 2016 CTS-V will sprint to 60 miles per hour in just 3.7 seconds, on its way to a top speed of 200 miles per hour. Naturally, Cadillac's engineers say they have tuned the CTS-V to ensure it can put all that power to the ground with the most precision and poise possible. That starts with the excellent Magnetic Ride Control active damping system (with a claimed 40-percent increase in responsiveness)and a 25-percent increase in structural stiffness that should improve overall handling and steering. What's more, a high-performance Brembo brake package comes standard, as do 19-inch alloy wheels wrapped in seriously sticky Michelin Pilot Super Sport tires that will reportedly offer 1g in lateral acceleration. Cadillac also says that all changes to the bodywork are functional. That includes a carbon-fiber hood, front splitter, rear spoiler and diffuser that are super light and aid with aerodynamics and weight reduction – all of which will be available as an optional package for folks who like the exposed carbon look. Inside, it's more of what we're used to on lesser CTS models, but there's newly optional carbon fiber trim, microfiber suede upholstery trim, and some seriously awesome Recaro seats. Additionally, as we exclusively reported earlier, Cadillac will offer GM's Performance Data Recorder in the CTS-V. It records high-definition video with data overlays that's sharable via social media. Beyond that, Cadillac will offer the usual smattering of tech goodies, including Siri Eyes Free, OnStar with 4G LTE, CUE infotainment with navigation and Bose audio. The CTS-V will launch later next year, following the debut of the smaller ATS-V. In the meantime, the sedan will officially bow at the 2015 Detroit Auto Show in just a few weeks.

How GM's grueling 24-hour test gets the kinks out of its performance cars

One of the biggest challenges automakers face when designing a high-performance car is making sure that it is both fast and reliable. For General Motors, any car that might be taken to the track by its owner - like the Corvette, Camaro Z/28 (shown above) and the Cadillac CTS-V, for example - undergoes a rigorous and strenuous 24-hour test by engineers at the Milford Proving Grounds, as pointed out by Car and Driver.
We've posted on this topic in the past - on a video showing the Camaro ZL1 being brutalized, for instance - but this article gives a more in-depth look at what actually happens behind the scenes... including what that poor ZL1 went through. Though the test isn't for 24 hours straight, the cars are pushed as hard as possible by some of GM's best drivers with only the brakes and tires replaced frequently.
We don't want to ruin the fun for you, but it is an interesting article that tells just some of what GM does to develop its sports cars. Check out the full article over at Car and Driver for the rest of the story.
