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.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Cadillac ELR next EV to get Plugless Power wireless charging tech

Evatran has been testing its Plugless Power wireless charging systems for electric vehicles in the Chevy Volt and Nissan Leaf for years now and made the tech commercially available early this year. With the growth of the EV market, Evatran is getting ready to expand as well. The company announced today that it will add three premium EVs to the Plugless Power system by the end of the year, with the first (and so far only) named model being the Cadillac ELR. We expect it was not difficult for Evatran to adapt the Plugless Power system to the ELR, since the vehicle's powertrain is so similar to the one in the Volt. The main problem we see is that Cadillac has only sold 390 ELRs (as of the end of June), so this first Plugless Power expansion isn't exactly going to ignite sales, even if every ELR owner opts for the cool tech. If one of the next two announcement is for the Tesla Model S, though, then you're talking numbers. Speaking of the future, what models do you think will be next? The Plugless Power L2 wireless systems were recently declared safe by the Intertek and start at $2,470, not including installation or government incentives. All the online/smartphone connectivity features that work with the car when it's got a cord stuck in it work with the L2 system, Evatran says. Orders start today, and the ELR package will be available September 1. There's more, including a local news report on the technology, below. WSLS 10 NBC in Roanoke/Lynchburg Va Wireless Vehicle Charging available to Cadillac ELR owners starting September 1st The Cadillac ELR Joins the Growing List of Compatible Electric Vehicle ("EV") Models from Evatran, the World Leader in High-Power Wireless Charging RICHMOND, VA July 28, 2014 – In an exciting statement today, Evatran Group, Inc. ("Evatran"), announced that its PLUGLESS wireless charging technology would soon be available on the Cadillac ELR. Evatran, the first Company in the world to make wireless charging available to individual EV drivers, currently has systems that are compatible with the Nissan LEAF and Chevrolet Volt. The Cadillac ELR is the first model to be announced in what is intended to be three new premium model announcements by the end of 2014. Evatran will begin accepting advanced orders today for deliveries as soon as September 1st. "The launch of the Cadillac ELR system is an important milestone for us," commented Rebecca Hough, Evatran CEO and Co-Founder.
