Cadillac's Super Cruise — look, Elon, no hands!

Cadillac is about to start selling vehicles with an autonomous driving mode and TechCrunch got an early look at the technology in a production car. "Wait for the green light and let go," the Cadillac engineer instructed. That's it. The car was driving itself. I, the person behind the steering wheel, was no longer the driver. Cadillac's Super Cruise system was driving. The 2018 Cadillac CT6 sped along U.S. 23 under the direction of Super Cruise. Traffic was light and the weather was perfect. The system held the Cadillac sedan in lane and responded appropriately to traffic. I spent an hour on the expressway and touched the steering wheel and pedals only a few times. Super Cruise made the drive boring. I think that's the point. Here's how it works Super Cruise is available once the driver navigates the vehicle onto an expressway. When ready, a little icon is displayed by the speedometer and the driver hits a button on the steering wheel to switch it on. Once the light bar on top of the steering wheel turns green, the driver can let go. Super Cruise is driving.This steering wheel light bar is key to the operation. When green, the driver knows Super Cruise is in control. Blue means the driver interrupted the system to change lanes and red means Super Cruise needs the driver to confirm they're paying attention and not checking Twitter. When active, Super Cruise controls the steering and speed, but again, only on an expressway. This is done through onboard sensors and using GPS and mapping data. GM employed GeoDigital, a startup in GM Venture's portfolio, to map 160,000 miles of expressways in the U.S. and Canada. The car company then used Super Cruise-equipped vehicles to test each mile. This combination of onboard systems combined with map data makes the system feel polished and sophisticated. During my admittedly limited time in the vehicle, the CT6 precisely held its position in the lane and confidently handled sweeping curves at speed. There was no wiggling or squirming — from the Cadillac or myself. The car was in control, and I felt safe. Although the driving conditions were perfect for my test ride, during adverse weather, the system will work normally until one of the key systems is unable to operate.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

2016 Cadillac CTS-V to hit dealers this summer, start at $83,995*

Cadillac has announced pricing for the 640-horsepower CTS-V, and not only will the new super-sedan outgun its heartiest German rivals, it'll undercut them on price, too. Kicking off at $83,995 (not including a $995 destination charge), the CTS-V is nearly $10,000 less than the 560-hp BMW M5, almost $18,000 less than the 577-hp Mercedes-Benz E63 AMG S 4Matic, and is nearly $25,000 less than the 560-hp Audi RS7. So in case you were wondering, yes, the CTS-V will continue to be one of the auto industry's very best high-performance bargains in its third generation. "V-Series represents the pinnacle of Cadillac, a brand that now makes drivers' cars at the highest level," Cadillac's head honcho Johan de Nysschen said in a statement. "The new CTS-V is essentially two cars in one: a luxury sedan with sophisticated road manners and a track-capable sports car with awe-inspiring performance. This type of car is exclusive, the domain of the few who can access this level of incredible capability. V-Series matches or overtakes the finest cars in this elite class, while being more accessible." As for when you can get your hands on bargain-priced beast, dealers are now accepting orders, with deliveries slated to begin late this summer. Scroll on down for the official release from Cadillac.

Not only are the new V-Series cars elevated in terms of performance, they now reach a broader spectrum of drivers by presenting two distinct personalities, size categories and price points. With a top speed of 200 mph and 0-60 performance in 3.7 seconds, the CTS-V is the most powerful car in Cadillac's 112-year history. The 2016 CTS-V is priced from $83,995.
