2020 Cadillac CT4-V, CT5-V revealed, less powerful than predecessors

Expectations have reached stratospheric heights for the 2020 Cadillac CT4-V and 2020 Cadillac CT5-V, and for good reason: Their ATS-V and CTS-V predecessors were potent sports sedans with gobs of power and handling and braking to match. Now the new sedans have been revealed, and they're not what we expected. They each lose two cylinders compared with the other vehicles, and on paper, they don't look as capable. But we do have hope that these won't be the end-all, be-all performance Cadillacs. First, let's look at the cars. The CT4-V will be the base of the V brand, and it's our first look at the small luxury sedan. It has a roofline and window treatment more like past Cadillacs, eschewing the C-pillar garnish of the CT5. It also naturally gets dark trim and headlights, a unique spoiler and quad tailpipes to distinguish it as a V. Under the hood is a turbocharged 2.7-liter four-cylinder that is based on the engine in the new Chevy Silverado. It makes 320 horsepower and 369 pound-feet of torque, a far cry from the ATS-V's 464 horsepower and 445 pound-feet of torque. Cadillac CT4-V View 12 Photos Power goes through a 10-speed automatic transmission only. Both rear-wheel drive and all-wheel drive are available. It gets a mechanical limited-slip differential whereas the ATS-V had an electronically controlled limited-slip differential a la Camaro ZL1. The brakes have four-piston calipers at each corner versus six-piston front units and four-piston rear units on the ATS-V, and the rotors are smaller. Magnetic Ride Control remains standard on the rear-drive version, but the all-wheel-driver version sticks with conventional shocks. The new CT4-V is about 200 pounds lighter than the ATS-V, though, and it has 50/50 weight distribution. Additionally, both the CT4-V and the CT5-V have Super Cruise available as an option. Moving on to the CT5-V, it looks like a regular CT5 but with dark trim and lights, quad tailpipes and a unique rear diffuser. Instead of the CTS-V's 640-horsepower supercharged V8, the CT5-V uses a twin-turbo 3.0-liter V6 making 355 horsepower and 400 pound-feet of torque. Changes made to the 3.0 for the CT5-V include a new intake system and new exhaust, and it revs higher too. Like the CT4-V, it comes with a 10-speed automatic and either rear-wheel drive or all-wheel drive. It does get the electronically controlled limited-slip differential.

Infiniti Q50 Red Sport 400 priced at $48,855, AWD at $50,855

Infiniti's most powerful production model, the new Q50 Red Sport 400, now has a starting price. You'll need at least $48,855 for the rear-drive model or $50,855 for all-wheel drive. (Both figures include the $905 destination charge.) A fully loaded, rear-drive Q50 RS400 with Direct Adaptive Steering, navigation, adaptive cruise control, a heated steering wheel, and Infiniti's entire alphabet soup of safety equipment, tops out at $57,045. (Again, add $2,000 for AWD). When it comes to rear-drive competition, the closest base price to the Q50 is the 320-hp BMW 340i. This German undercuts the Infiniti by two grand, $46,795 to $48,855. But the BMW outprices the Q50 as soon as you start selecting options. A 340i with similar equipment to a loaded Q50 Red Sport 400 costs just under $60,000. All-wheel-drive German competitors also lose out in the price war. Like with the rear-drive models, the BMW 340i xDrive undercuts the Q50 RS400 by around $2,000. Add the options, and the Infiniti becomes a better value. The other two big German rivals, the Audi S4 and Mercedes-Benz C450 AMG start at a higher price and only get more expensive. Technically the S4 starts cheaper than the Q50, but only with the standard manual transmission. Selecting the S-Tronic dual-clutch model kicks the price from $50,125 to $51,125, and going for the top-end Prestige trim will bump potential Audi owners up to $57,025. Throw on must-have S4 options, including adaptive cruise control, adaptive dampers, and a sport differential and you'll be shell out $64,425 for the Audi. The Mercedes-Benz C450 AMG is the priciest choice in this group, starting at $51,725, or roughly $900 more than a base Q50 RS400 with AWD. Options, again, are the downfall here. Building a C450 to match a loaded Infiniti will drive the Mercedes' price up to $64,315. While it occupies something of a weird space relative to these vehicles, it's also worth mentioning the Cadillac CTS VSport. It's the only car in this impromptu pricing comparo that can outgun the Q50, with its 3.6-liter, twin-turbo V6 good for 420 hp and 430 lb-ft of torque. It also starts at $60,950, although that includes plenty of standard equipment. All this means that the Q50 Red Sport 400 represents a relative value. It packs more power than the Germans – 80 more than the 340i, 67 more than the S4, and 38 more than the C450 – and a more comprehensive list of options, too.

GM shows off 'digital vehicle platform' enabling more in-car tech and OTA updates

It appears to have dropped the sobriquet "Global B," but General Motors' new electrical architecture has bowed in drawings and video. This is the "digital vehicle platform" GM president Mark Reuss spoke to Reuters about in 2015, saying it would move a great deal of a vehicle's computer work to the cloud and enable over-the-air updates. Reuss took the microphone for the debut, too, saying, "Our new digital vehicle platform and its eventual successors will underpin all our future innovations across a wide range of technological advancements, including EVs and expanded automated driving." The system will go into production later this year, appearing in dealerships first either on the 2020 Cadillac CT5 or the mid-engined 2020 Chevrolet Corvette. Yes, these are the same electronics cited for delaying the launch of the C8 Corvette over excessive draw, security and getting the more-than-100 computer modules to communicate seamlessly. When Car and Driver asked about that, GM replied with "No comment." Volkswagen's having the same issues with the Mk8 Golf right now, though, so GM isn't alone, and this will be the new normal among OEMs for a while. What's certifiable is that the new architecture is robust enough to handle 4.5 terabytes of data per hour, which is five times what GM's current wiring can handle. And thanks to Ethernet connections of 100 Mbps, 1 Gbs and 10 Gbs, communication within and without the vehicle happens much faster. The advances mean better screen resolutions, better battery management for hybrids and electric vehicles, the capability for over-the-air updates and "functionality upgrades throughout the lifespan of the vehicle." Cadillac's Super Cruise has already been lined up as a leading candidate for constant improvements in the driving assistance suite, a key part of GM's "vision for a world with zero crashes, zero emissions and zero congestion." And whenever GM decides to take the plunge, it will mean a 48-volt electrical system. More than 300 specialists worked on the digital platform, and security was a huge part of the task. We've already heard that GM consulted with Boeing and military contractors on how to prevent hacking. The carmaker has an internal Product Cybersecurity group that reached out to the research community, and created a "bug bounty" program to crowdsource uncovering any flaws.
