McLaren, Koenigsegg, Toyota, Ford, Dodge and Corvette Lego kits announced for 2021

Lego has announced a slew of car-themed sets for 2021. The six kits comprise nine vehicles and fall under the brick pusher's Speed Champion line of official OEM-licensed kits. News of their arrival comes from German toy retailer JB Spielwaren's pre-order listings, which show three single-car sets and three dual-car sets of matched marques. Starting with the McLaren Elva roadster, the kit consists of 263 pieces and is finished in blue. It seems to have a difficult time capturing the curves of the real-life Elva, but there's only so much you can do with a bunch of plastic blocks. Lego has made several other McLaren kits before, including the Senna, 720S, and a more advanced Senna GTR for the Technics line. Next up is the Koenigsegg Jesko, made up of 280 pieces and finished in white. Though the real-life Jesko is still curvy, this kit does a better job of replicating its aggressive maw, vents and cantilevered rear wing. Rounding out the single-car sets is the 299-piece Toyota GR Supra in yellow. This marks the first time Toyota has lent their license to Lego. Again, it struggles a bit to represent the curvy Supra, relying on printed details like logos and headlights to identify. On the other hand, the Chevrolet two-car does a stupendous job with the 1968 Corvette. The C3 is instantly recognizable as such. The C8-R race car it's paired with suffers from the same issues as some of the previous cars, though. The set contains 512 pieces, and funnily enough the C8 driver has short hair while the C3 driver sports a period-correct wavy mane. The next set is a 627-piece Mopar-themed pair, including a purple (Plum Crazy?) 1970 Dodge Challenger T/A and an SRT top fuel dragster. The race car is spot on, but the Challenger was probably tough to make given the width restrictions. It looks a couple of pegs too narrow compared to the wide proportions of the real deal. Last but not least, the Ford set contains a Bronco R and Ford GT Heritage Edition. Consisting of 660 pieces, the set does an excellent job of representing both cars. The GT looks faithful in its Gulf livery, and the Bronco R looks more like a real Bronco than the actual Bronco R race truck. All in all, it's always fun to see more Lego sets with real cars, and we're glad to see more manufacturers added to the roster. The single-car sets are recommended for ages 7 and up, while the double-car sets have an 8 years and up rating. Price in U.S.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.

Chevy Corvette gets Valet Mode with Performance Data Recorder [w/video]

For the 2015-model-year, Chevrolet introduces Valet Mode for the Corvette, an enhancement to the Performance Data Recorder (PDR) already available and to your peace of mind. The PDR already captures 720p HD video with a windshield-mounted camera, records interior audio with a cabin microphone and gathers telemetry data using GPS, saving the data to an SD card in the glovebox. You can then watch your track-day antics with various information overlays on the center console screen.
Valet Mode will let you hit 'Replay' when your car gets pulled up front smelling vaguely of fricasseed clutch. Turned on by entering a four-digit code, it also locks the interior storage spaces and turns off the infotainment system. It can't be turned off until the code is re-entered. There's a press release below with more information as well as a video that explains how it works, with the obligatory dig at the 'Vette's biggest foe.
