2016 Cadillac CTS-V First Drive [w/video]

A million insects lost their lives today. Boxelder bugs and mayflies making the ultimate sacrifice in Elkhart Lake, their carapaces no buffer against a rocketing rectangle of safety glass. Their bodies gorily streaking into spangles along the diamond-faceted face of the Cadillac CTS-V. Road America is a four-mile ribbon of pavement snaking its way through the emerald center of the country's northern heartland. Since the 1950s it's seen uncountable fields of diverse racing machinery rocket over its hills and around its 14 corners. I would imagine that on those occasions the tramping of onlookers and hubbub of vehicles, both competitive and commonplace, would dissuade a great number of our six-legged friends from making their way onto the track. But today it's just me turning laps. Inconceivably just one journalist, driving the baddest roadgoing Cadillac ever made, on one of the loveliest circuits America has ever carved out. So big-winged bugs made it out to me in a vast array and a tragic sum, and I drilled through them oblivious to anything but one of the greatest days of driving I've ever had. Cadillac has turned its CTS-V from a performance sedan to a monster. For 2016 Cadillac has turned its CTS-V from a performance sedan to a monster worthy of the carnage described above. The words "epic" and "awesome" are hilariously overused on the Internet, but in the case of the CTS-V's 6.2-liter supercharged V8, their literal meanings are fitting. The capacity to produce 640 horsepower and 630 pound-feet of torque is astounding. Feeling those outputs come to growling life under my foot arch, uncorks different reactions in my brain as the day wears on: first trepidation, next cautious optimism, finally red-eyed bloodlust. A glance at the power and torque curves will show you that the charged V8 behaves more like a naturally aspirated thing than a turbo'd on/off switch. Peak torque arrives at 3,600 rpm, horsepower at 6,400, giving the engine lovely, linear power delivery. Even with top torque happening near the middle of the tach, there's no small amount of the stuff when the engine first spins up, so launching all 4,145 pounds of Detroit iron still feels exotic. Launching all 4,145 pounds of Detroit iron still feels exotic. On the roads around Wisconsin, using all of the available power is hardly advisable, but I have no trouble driving this fast car slowly (sort of).

Here's how Cadillac made its Magnetic Ride Control suspension quicker and smarter

Bugatti makes the world's fastest car, but Cadillac claims it has developed the world's fastest suspension. Its fourth-generation Magnetic Ride Control technology receives hardware and software tweaks to deliver a more comfortable ride and sharper handling. It's offered on some variants of the CT4, CT5 and the Escalade. Introduced in 2002 on the Seville STS, this self-adjusting suspension is not as complicated as it might sound. It relies primarily on electromagnets that emit a magnetic field, and a magnetorheological fluid whose viscosity changes depending on the strength of the magnetic force. Sensors scan the road up to 1,000 times per second and send the information they gather to the electromagnets, which then alter their magnetic field as needed to modify the fluid's viscosity. The fluid is in the shocks, so making it thicker returns a firmer ride, and vice versa. In simpler terms, Magnetic Ride Control leverages chemistry and physics to make the ride sporty, comfortable, or somewhere in between -- all in the blink of an eye. By reacting to the changing magnetic field, the fluid-filled shocks filter out road imperfections and maximize tire contact with the road to deliver more precise handling. Cadillac began developing the fourth-generation system by improving the hardware. The in-wheel accelerometers are more accurate than before, the inertial measurement unit is more precise, and the damper fluid formula was changed for quicker response times and a smoother ride. Engineers then turned their attention to the system's software. They notably gave the sensors the ability to process a wider selection of input and output signals, which translates to a wider spread between comfort and sport. And, they made the response time up to 45-percent quicker. All told, the fourth-generation Magnetic Ride Control technology performs better under heavy braking and hard cornering, it delivers more consistent performance, and it reads the road more accurately. Cadillac proudly notes these are the most comprehensive updates it has made to the system in nearly two decades. Magnetic Ride Control comes standard on the 2021 CT4-V and the 2021 CT5-V, and it's bundled into the CT5's V Performance package, which also includes a mechanical limited-slip differential. It's also standard on the Sport and Platinum variants of the 2021 Escalade, and it's part of the Premium Luxury trim's Performance package.

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.
