Cadillac’s most powerful engine ever

Published

on

2022 Cadillac CT5-V Blackwing

The 2022 Cadillac CT5-V Blackwing is the most powerful production car ever from General Motors’ luxury brand. “Engineering Explained” host Jason Fenske has all of the details on the new performance sedan’s monster engine.

Blackwing is the name of both an engine and the highest tier of Cadillac’s performance models. But the CT5-V Blackwing doesn’t use the Blackwing engine, which was a 4.2-liter twin-turbocharged V-8 that debuted in the discontinued CT6-V sedan. Instead, Cadillac chose the supercharged 6.2-liter V-8 from the CT5-V Blackwing’s predecessor, the CTS-V. However, the engine is now tuned for 668 horsepower and 659 pound-feet of torque, compared to the previous 640 hp and 630 lb-ft.

The 6.2-liter supercharged V-8 is in turn based on the LT4 engine that debuted in the C7-generation Chevrolet Corvette Z06 for the 2015 model year. It’s also a pushrod engine, while the 4.2-liter twin-turbo V-8 boasted dual overhead cams. Its turbos were also located between the cylinder banks in a “Hot-V” arrangement for better responsiveness.

In the CT6-V, the 4.2-liter engine made 550 hp and 640 lb-ft of torque, which is actually more hp per liter than the larger supercharged engine. In the all-wheel drive CT6 sedan, the Blackwing engine even achieved better fuel economy than the LT4 engine in the C7 Z06, Fenske noted. So why did GM opt for the Chevy-derived engine over the Cadillac-specific one?

First, the supercharged engine can rev higher than the twin-turbo engine—6,600 rpm versus 6,000 rpm. The 6.2-liter engine is also fairly compact for its displacement, Fenske said (remember, it was designed to fit under the low hood of a Corvette). It’s also more responsive, he noted. Even if you disagree with the choice of engine, it’s also worth noting that the CT5-V gets a standard 6-speed manual transmission—something that wasn’t available in the CT6-V or CTS-V sedans.

The CT5-V Blackwing may also be one of the last of its breed. Just before unveiling the supercharged sedan, GM announced that it “aspires” to eliminate tailpipes from all of its passenger cars and light-duty trucks by 2035. While aspiration is different from commitment, it’s a sign that the internal combustion’s days are numbered at America’s largest automaker. Even before the announcement, Cadillac was already expected to go mostly electric within the next decade, starting with the Lyriq SUV and Celestiq sedan.

Turn back time with this retro 2021 Ford F-150

2021 BFP Retro Ford F-150

After launching a retro design package for the Ford F-150 about two years ago, Ohio dealership Beechmont Ford is back with another version for the redesigned 2021 F-150.

First spotted by Motor1, the 2021 BFP Retro Ford F-150 features basically the same ingredients as before, including a two-tone vinyl wrap, retro 17-inch wheels wrapped in 35-inch all-terrain tires, and a 3.5-inch lift kit. A chrome bed rack and KC Hi Lights complete the look. The default Satin Pearl wrap can also be substituted for actual paint.

While the previous retro F-150 was based on the XLT trim level, the 2021 model shown here is based on the higher-level Lariat model. You can still get the retro package on an XLT, or a different 2021 F-150 trim level should you desire. Beechmont Ford does recommend the factory Chrome Package, which matches the bed rack and polished wheels.

Beechmont is asking for a $500 deposit on the package. Customers must order their trucks directly from Ford and specify delivery to Beechmont, which will then add the retro extras.

The dealership noted that wait times are longer than usual due to the global microchip shortage, which has heavily impacted truck production. It’s currently estimating a six-month wait time for delivery.

Beechmont doesn’t just do retro trucks. This is also the dealership that began offering a 750-hp supercharged Ford Mustang for $44,994 last year. Beechmont takes a stock 5.0-liter V-8 Mustang GT and adds a Roush Phase 2 supercharger, which is normally a $7,999 item on its own. You even get a 3-year/36,000-mile warranty.

Should you use racing oil in your road car?

Published

on

Ford Mustang NASCAR Xfinity Series race car

Every part of a modern race car is optimized to extract maximum performance—including the fluids that go into it. Specialized racing oil is a must in the paddock, but is it a good idea to use that in your road car?

“Engineering Explained” host Jason Fenske answers that question in this video, talking to engineers from Mobil1 (which also sponsored the video), engine builder Roush Yates Engines, and NASCAR team Stewart-Haas Racing.

First off, Fenske emphasizes that racing engines don’t have much in common with road-car engines. Pushrod V-8s like the ones used in NASCAR disappeared from the average American car decades ago, and racing engines in general have a very different duty cycle. They’re flogged (a NASCAR V-8 can rev to 10,000 rpm and spend 90% to 95% of a race at full throttle), but also have fairly short maintenance intervals. NASCAR engines have their oil changed about every 500 miles and are only expected to last about 1,500 miles, Fenske noted.

NASCAR oil is also fairly unrestricted (rules can vary by race series), giving teams more leeway to look for competitive advantages, Fenske said. Teams tend to use thinner-weight oils to reduce frictional losses and maximize power. That’s not great for longevity but, remember, the engine only needs to last 1,500 miles. Road-car engines, on the other hand, are expected to last hundreds of thousands of miles, so that kind of tradeoff isn’t possible.

Racing oils and road-car oils do have some commonalities, though. They use a lot of the same additives, such as detergents, dispersants, anti-foaming agents, antioxidants, and rust inhibitors, Fenske noted.

However, the difference is in the details. Oils used for road cars are designed to meet a long list of regulations and requirements set down by individual automakers. In NASCAR where, again, rules governing oil are fairly loose, teams can optimize an oil for one specific engine design. It’s really that process that makes racing oil work, and it’s just not practical for individual road cars. Unless you have your own laboratory and a lot of patience, at least.
