1970 Chevy Camaro gets 650-hp crate engine for SEMA

The latest edition of the Chevrolet Performance catalog arrives at the 2015 SEMA Show, and to demonstrate the insane creations that are possible with it, the company has a seriously powerful machine in tow. This custom 1970 Camaro RS boasts the new LT4 crate engine that makes a staggering 650 horsepower and 650 pound-feet of torque. The offering gives hot rod builders the ability to put the Corvette Z06's 6.2-liter supercharged V8 into any project where they can make the mill fit. This Hyper Blue Metallic Camaro should offer neck-snapping performance with its massively powerful engine and a T-56 Super Magnum six-speed manual gearbox. Chevy's show car is about more than just packing copious horsepower into a classic shape, though. The builders also overhaul the suspension with coilovers at the front and rear, in addition to a four-link setup at the back. Behind the 19-inch aluminum wheels, the coupe has Z06-based brakes at both ends. For better visibility, it wears LED headlights and taillights. Plus, the interior gets custom gauges and a six-point roll cage. With pieces like titanium intake valves and forged aluminum pistons, the LT4 crate engine comes ready to offer serious performance, but Chevy also gives builders a few options to fit their application. The mill is available with either wet- or dry-sump lubrication. Depending on the version, there are kits to fit front-end accessories, air conditioning, and power steering, as well. The new Chevy Performance catalog features other high-performance components like Z06-based parts for the standard Stingray and an array of performance upgrades for the 2016 Camaro, including suspension lowering kits, brake upgrades, and more. We look forward to seeing this vast collection of goodies at SEMA this year.

The new crate engine – offered in dry-sump and wet-sump versions – allows builders to use the high-tech performance engine in their hot rod projects.

2016 Chevrolet Colorado Diesel First Drive [w/video]

The first thing you notice inside the diesel Chevy Colorado is that it's quiet. Almost too quiet. A lot has been done to quell noise and vibration with this new powertrain, and it shows – or rather, doesn't. There's some characteristic diesel clatter at idle, but even then it's distant and practically disappears as you start moving down the road. At full throttle, when the engine is at its noisiest, the sound isn't particularly diesel-like, just a pleasant intake breath. The accompanying smoothness is almost eerie. When we ask where all the noise went, Chevy's engineers, marketing guys, and PR reps all explain that this refinement is what Americans want. We're still not sure. This is a truck, after all, and the diesel pickup customer is different from the guy buying a diesel Cruze for his highway commute. Chevy contends that they're also not the same as the buyer of a Silverado HD. Although this 2.8-liter Duramax four-cylinder has been in service elsewhere around the globe, its first US application is in the Colorado and its GMC Canyon twin. The engine puts out 181 horsepower and 369 pound-feet of torque, and it does so unobtrusively as a result of a lot of modifications for our market. To keep normal diesel sensations out of the cabin, the intake and oil pan both get acoustic treatments. A new, thicker material is used for firewall sound deadening. Redesigned balance shafts have tighter tolerances to increase smoothness. The diesel powertrain is smoother than the Colorado's gasoline V6. One of the more interesting and certainly unexpected vibration-reduction changes is a special torque converter from German supplier LuK equipped with a centrifugal pendulum absorber. This pendulum spreads from the center of the torque converter as engine speed increases and is tuned to absorb the four-cylinder's second-order vibrations, not just those in a narrow frequency band. It does an admirable job, especially considering the engine's biggish, 0.7-liter cylinders, which lead to bigger vibrations. The result is a powertrain that's smoother than GM's (not particularly smooth) corporate V6, which is available in the standard Colorado. It's quieter than a Cruze diesel and even out-softens some gas direct-injection engines on the market. Paradoxically, it may be the most refined of all of the Colorados. No vibration comes through the steering wheel, pedals, floorboards, or even the rearview mirror. But you can tell it's a diesel when you hit the throttle.

Made in America | These cars top the most-American list

The car with the most American/Canadian content for 2022 is ... cue the drumroll ... the Lincoln Corsair, in both standard gasoline-fueled and plug-in hybrid guise. Both versions of Lincoln's compact luxury crossover earned a score of 86 — due to 72% of its parts coming from one of the two aforementioned countries — in the American University Kogod Business School's annual "Made in America Auto Index." Last year's leader, the 2021 Ford Mustang GT (when equipped with a manual transmission) fell all the way to 22nd place with a 50% rating due to a switch in transmissions sourced from Mexico. In case you're interested, that puts Ford's red-blooded American ponycar below vehicles like the Kia Sorento, Mercedes-Benz GLE-Class SUV and Lexus ES. If you're wondering how an American car that's assembled within the borders of the United States could rank below a model from a Korean, German or Japanese automaker, well, we'll let Kogod explain: "The components of the index are based on research performed by the Center for Automotive Research in Ann Arbor Michigan regarding the economic value of different components of auto manufacturing. For example, the highest ranked cars are made by U.S.-based manufacturers using American engines and transmissions, and with a high AALA percentage of U.S. and Canadian parts." There are 25 total vehicles listed in the Top 10 (there are lots of ties this year). Here's the full list: (1) Lincoln Corsair: 86 (1) Lincoln Corsair PHEV: 86 (2) Tesla Model 3 Long Range: 82.5 (3) Chevrolet Corvette Sting Ray: 81 (4) Chevrolet Colorado: 80.5 (5) Jeep Cherokee Latitude 4x4: 80 (5) Jeep Cherokee Trailhawk: 80 (5) Tesla Model 3 Performance: 80 (5) Tesla Model Y: 80 (6) Dodge Durango Citadel: 79.5 (6) Dodge Durango Blacktop AWD: 79.5 (7) Honda Passport Trailsport: 78.5 (8) Ford F-150 2.7L, 3.3L, 5.0L: 77.5 (8) Ford Ranger: 77.5 (8) Ford Bronco automatic: 77.5 (8) Tesla Model S: 77.5 (8) Tesla Model X: 77.5 (9) Jeep Grand Cherokee Laredo 3.6L: 77 (9) Jeep Grand Cherokee L LTD: 77 (9) Jeep Grand Cherokee Overland 3.6L: 77 (9) Chevrolet Camaro automatic: 77 (10) Honda Odyssey: 76 (10) Honda Ridgeline: 76 (10) Honda Pilot: 76 There's a whole long list of reasons for the above scores, with seven criteria that include factory location, headquarters location and where its various bits and pieces come from.
