2021 Subaru Crosstrek driven, and EV performance kings | Autoblog Podcast #647

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Consumer Editor Jeremy Korzeniewski. They kick things off by talking about Jeremy's recent drive in the new 2021 Subaru Crosstrek. They compare the BMW X1, BMW X2 and Mini Countryman before providing another take on the Cadillac CT5. Recent Lucid Air and Tesla Model S news has them wondering if electric cars are the new performance kings and end with a quick discussion on California's intent to zero emissions by 2035.

2022 Cadillac CT5-V Blackwing, CT4-V Blackwing bring big performance back to the brand

They're finally here, the real successors to the Cadillac CTS-V and ATS-V: the 2022 Cadillac CT5-V Blackwing and CT4-V Blackwing. And at least on paper, they sure seem like worthy successors to those superb super sedans. They're more powerful, come with standard manual transmissions, and feature the latest and greatest chassis upgrades available. We'll start things off with the most beastly of the Caddies, the CT5-V Blackwing. Like the CTS-V predecessor, the Blackwing gets a supercharged 6.2-liter pushrod V8. But thanks to intake and exhaust improvements, output is up to 668 horsepower and 659 pound-feet of torque, as opposed to the CTS-V's 640 horses and 630 pound-feet. The engine also is handbuilt in Bowling Green, Ky., just like the short-lived turbocharged DOHC Blackwing V8. It's coupled either to a six-speed manual transmission with a twin-disc clutch, rev matching and no-lift shifting, or a 10-speed 10L90 automatic transmission. Power goes to the electronically controlled limited-slip differential at the rear, and rear-wheel drive is the only drive configuration available. The transmission and differential each get their own oil coolers, too. Cadillac says the CT5-V Blackwing should be able to hit 60 mph in 3.7 seconds with the automatic transmission, and the top speed is over 200 mph. 2022 Cadillac CT5-V Blackwing View 13 Photos As for the CT4-V Blackwing, it gets a twin-turbocharged 3.6-liter V6 built in Canada, and although it is more powerful than the previous car, it's only by a small amount. The CT4-V Blackwing makes 472 horsepower versus the ATS-V's 464, and the 445 pound-feet of torque is the same between each car. Just like the CT5-V Blackwing, the CT4-V gets either the same six-speed manual transmission or a 10-speed 10L80 automatic transmission, the electronically-controlled limited-slip differential, and the oil coolers. Picking the manual transmission has extra perks on the CT4-V Blackwing, though. The engines in manual cars received titanium connecting rods and revised crankshaft counterweights. The manual transmission's no-lift shift functionality is also more helpful on the CT4-V Blackwing since it keeps the car in boost between gears. Still, Cadillac's 0-60 mph time estimate is for the automatic model at 3.8 seconds. Top speed is 189 mph. 2022 Cadillac CT4-V Blackwing View 16 Photos Keeping all that power under control are a variety of chassis upgrades.

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.
