Cadillac teases CT4 and CT5 V-Series Blackwing steering wheel

There's quite a bit that we know about the upcoming Cadillac V-Series Blackwing models. Thanks to spy shooters and prototypes, we've seen the CT4-V and CT5-V Blackwing out and about testing on public roads, which means we've seen the bronze wheels in staggered sizes. We've been told they will offer proper manual transmissions, and we know they will lap a race track quicker than the ATS-V and CTS-V they replace. And now we know what their steering wheels will look like. It's not much to base an entire teaser on, but there are a few interesting tidbits we can glean from Caddy's first official Blackwing tease. First, the wheel itself. It's leather wrapped (not Alcantra, at least on this example), it looks to have meaty bulges where you'll want to grip it, it has a red strip at the top to help locate straight ahead while driving aggressively, and it has a carbon fiber V-shaped spoke at the bottom. Finally, we see a prominent silver button labeled "V" on the left side that will allow drivers to quickly access V-Mode. To the right will be buttons for the Performance Traction Management system. Judging by the fuzzy background behind the wheel that shows some sort of digital gauge cluster, it seems that Cadillac may be aiming for a 200-mile-per-hour top speed for the CT5-V. That's not a stretch, as the last-generation CTS-V could hit that speed, too. Cadillac smartly took this shot in a way that blurs the center console, which means there's plenty more time to speculate on the transmission choices. Cadillac says the V-Series Blackwing models will be ready in time for the summer of 2021. Stay tuned. Related Video:  

Junkyard Gem: 1979 Cadillac Eldorado Biarritz

The Cadillac Eldorado lost a foot of wheelbase and 1,200 pounds when GM's luxury front-drive platform got downsized for 1979, which turned out to be prescient timing considering the massive spike in oil prices in the wake of the 1979 Iranian Revolution. The General kept the pricey Biarritz option package from the previous generation, adding a stainless-steel roof in the process. Here's one of those cars, found in a chilly Denver boneyard last month. The stainless-steel roof panel, inspired by the one used on the 1957 Eldorado Brougham, identifies a 1979-1985 Eldorado as a genuine Biarritz. This generation of Eldorado Biarritz achieved its greatest renown as the car bomb that detonates when pink-suited Ace Rothstein (Robert De Niro) cranks the starter in the 1995 film Casino. Naturally, a 24 Hours of Lemons team obtained one of these cars and raced it while the pit crew wore pastel suits and sipped from Tangiers Casino highball glasses. The MSRP on the base '79 Eldorado was $14,240 and the Biarritz package with leather seats tacked on an additional $2,600. That's $64,495 in 2021 dollars, at a time when plenty of car loans had interest rates approaching 20%. The '79 Seville's base price was higher ($15,646), despite being based on the lowly Chevy Nova, but that difference was erased by the cost of the Biarritz package. The Fleetwood limos were the only pricier Cadillacs that year. Yes, you had to be a true high-roller to purchase a '79 Biarritz. Of course, a new Mercedes-Benz 450SLC cost a terrifying $32,858 (about $125,850 today) that year, but the $13,067 Lincoln Mark V (the price went up substantially if you got one of the editions designed by Bill Blass, Givenchy, or Emilio Pucci) was close competition for the Biarritz. The 1979 Eldorado had something the Lincoln didn't, however: electronic fuel injection. Yes, a 350-cubic-inch (5.7-liter) Oldsmobile V8 engine with a pretty-modern-for-1979 throttle-body fuel-injection system sent 170 horses to the front wheels via GM's impressive Unitized Power Package longitudinal-engine front-wheel-drive system. Look at all those futuristic devices in that faux-wood dash! That stereo cassette deck added $225 ($860 today) to the price. Cruise control cost $137, the rear defogger added $101, and… well, you get the idea. This Cad is a bit tattered and has some rust spots here and there, but wouldn't have been an overwhelmingly difficult restoration.

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.
