Performance cars overpower the Detroit Auto Show

At precisely the stroke of noon on Monday, the 2016 Acura NSX rolled on stage at the Detroit Auto Show amid plumes of smoke and dancing lights. The sounds of the powerful engine revving soared to the rafters. It was the second coming of Acura's iconic sports car, and the reveal had all of the expected trappings. Afterwards, champagne corks popped and the bubbly flowed. It was noon in Detroit, but for the green-car movement, it seemed like the clock had struck midnight. That's an exaggeration, but performance was the overwhelming theme of North America's most important show. Ford – which has helped lead the way in smaller displacement engines and early adoption of hybrid powertrains – had more than 1,500 horsepower on stage one point after it revealed the GT concept, the new F-150 Raptor and the Shelby Mustang GT350R. The NSX is technically a hybrid (it has three electric motors), but with 550-plus hp, there's no doubt this Acura was bred on the track. The theme continued throughout the show at nearly every stand. Alfa Romeo showed off the 4C Spider, which is the open-air version of a car that purports to be the spiritual successor of the high-performance 33 Stradale from 1967. On Tuesday, Cadillac is scheduled to reveal the 640-hp CTS-V with the V8 transplanted from the Corvette Z06, and the Lexus was expected to roll out its own V8-powered beast, the 467-hp GS F. For enthusiasts – especially enthusiasts with money – these are halcyon days. But make no mistake, all of this power has a purpose. Ford product chief Raj Nair said the Blue Oval uses high performance cars to develop technologies, like aerodynamics and materials, which are then shared across its lineup. "It's another proof point about how serious we are in developing innovation through performance," he said. Ford, which is rolling out at least 12 performance cars by 2020, said the sporty cars attract younger and more influential buyers to its fold, which can help burnish its image beyond adding sales volume. Toyota is taking a similar approach, senior vice president Bob Carter said, noting the Lexus RC coupe draws people into showrooms and gets them excited about the brand, even if they don't end up buying one. "They provide an aspiration and a halo that provides the attention that gets you noticed in a cluttered market," he said.

GM will recall 3.5 million pickups and SUVs to fix brake issue

WASHINGTON — General Motors Co is recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and increase the risk of a crash. The recall, which covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles, was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted Wednesday. NHTSA opened a preliminary investigation into the issue in November 2018, and said it had reports of 9 crashes and two injuries related to the issue. It provided GM in July with additional field reports that prompted the automaker to open an investigation. The company did not immediately say on Wednesday how many injuries or crashes are linked to the issue but said it could impact braking in "rare circumstances." GM said dealers will reprogram the Electronic Brake Control Module with a new calibration that will improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Recalls Chevrolet GM GMC

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.
