2017 Cadillac CTS-V Drivers' Notes | V is for velocity

The 2017 Cadillac CTS-V is as close to a four-door Corvette Z06 as you're ever likely to get. Underneath the carbon-fiber hood rests one hell of an engine, a 640-horsepower supercharged V8. It's only slightly less powerful than what you'll find in the Corvette. Thanks to GM's chassis wizards, the car's handling is an equal match for the powerful engine. This particular car packs in a number of options, including Recaro seats and the performance data recorder that allows owners to measure lap times and record video. The most expensive option is the $6,950 Carbon Black Package. This nets you a carbon fiber hood vent, front splitter, spoiler and rear diffuser. This car isn't cheap, but it does undercut the less powerful Audi RS7 and Mercedes-AMG E63 S. Associate Editor Joel Stocksdale: This is a seriously fun, if also flawed, car. And the biggest contributor to the fun is the big lump of V8 under the hood. The supercharged 6.2-liter makes 640 horsepower, but Cadillac could've left the number off and just called it "effortless." The gentlest pressure on the gas pedal will result in you picking up an extra 10 mph without ever noticing. And when you stomp on it, you get this huge and immediate surge of acceleration. It's truly giggle-inducing. Although the CTS-V is big and heavy, it handles the power well. It gives you enough info on what's happening so you feel in control, and the chassis is impressively composed. The only real weak points I can find on the CTS-V (besides the low gas mileage) are the interior controls. They are abysmal. The infotainment screen is pretty poor, with a clutter of information at the main screen, and difficult-to-find commands for getting to other menus. But worse than that are the climate and volume buttons. They're all touch-sensitive spots on the center stack. They're not very responsive, and the vibratory feedback it provides isn't noticeable while driving. It doesn't help that the feedback feels pretty inconsistent, too. For me, I think I could learn to live with the infotainment, simply because I love the way the rest of the car feels and drives. But, Cadillac, you need to get to updating this ASAP. Associate Editor Reese Counts: OK, Cadillac's infotainment system sucks. Let's get that out of the way. Touch capacitive interfaces don't work well in cars. This does have the old version of CUE, so I'm hoping the next-gen system will fix some of the interface issues. Like Joel, this wouldn't turn me off from buying the car.

Book by Cadillac is like a streaming service for cars

Cadillac is launching a subscription-based service that gives users access to most of its models for a flat fee of $1,500 a month. Called Book by Cadillac, the program starts in February in New York City and its surrounding areas. Cadillac's goal: attract users who want flexibility without the costs and commitment of ownership. The monthly fee is steep, but Cadillac argues it's competitive with the cost of leasing a well-equipped luxury car. It also includes maintenance, taxes, and insurance fees. The Book service can also be stopped at any time, which frees users from any payments. There's no restrictions on mileage, though users pay for gas either by filling up the car when they're done with it or through a Caddy concierge who bills their account. Cadillac will deliver and pick up the vehicles from the user's choice of location via a white-gloved driver. Users can change vehicles up to 18 times per year, and they can be reserved with a mobile app. The theoretical goal is a Book user could head to the airport in New York in a Cadillac and reserve another one for their use in Los Angeles. Cadillac ran a test program last year and decided to move forward with Book after receiving a positive response on the price and features. "The overwhelming result is this is something competitive," spokesman Eneuri Acosta said. The program features the Escalade, Escalade ESV, CT6, CTS-V, ATS-V, and XT5 decked-out in Platinum trim. Other vehicles, like the non-V-series ATS or CTS could be added if there's demand. Book by Cadillac starts in New York, but will expand to other unspecified markets. Related Video:

Why an independent rear suspension for GM's new, full-sized SUVs wasn't easy

A Motor Trend report last month laid out how Cadillac's 4.2-lier twin-turbo Blackwing V8 could be an orphan due to cost concerns in the GM empire. Last-minute chassis changes to Cadillac's new sedans and XT6 crossover led to engine bays that couldn't fit the Blackwing. On the SUV side, according to the report, the new independent rear suspension for big people haulers cost so much to implement that GM ruled out reworking the Escalade to accept the Blackwing. At least one commenter rightly asked how could a suspension swallow that much money. A new piece in Motor Trend has the answer. The excellent Alissa Priddle spoke to Tim Herrick, GM's executive chief engineer for full-size trucks, about why the clean-sheet IRS cost "multimillions of dollars."  First, GM would need to build a new body shop at the Arlington, Texas plant that assembles the automaker's big SUVs to stamp the numerous wholly new parts and panels accommodating an IRS. Then GM would need to design and pay for a new assembly process. On top of those up-front costs, there was the incremental cost of the four-link IRS components being more expensive than those in the trucks' former leaf-sprung solid axles. Herrick endured so many rejections for so long that he remembers the date and time when he got approval for the new unit. He said it came down to a meeting where he told a higher-up, "I'll make you a deal: If we get to the reveal, or if we launch this and you think this was a dumb idea, I'll hand you my badge and let you walk me out." Head to Motor Trend to read the full story. Based on Herrick being on stage to help present the new SUVs to the press, and on our First Ride in the new Chevrolet Tahoe and Suburban at GM's Milford Proving Grounds, it appears this will have a happy ending for all involved. Furthermore, since Herrick worked on the T1 platform that supports the big SUVs as well as the light- and heavy-duty pickups, he understood the demands on the commercial side, too. That could be why when Roadshow asked Tim Asoklis, chief engineer of the Tahoe and Suburban, if the new IRS could endure life in the Chevrolet Silverado and GMC Sierra, Asoklis answered, "Oh, absolutely."
