2018 GMC Acadia with 'Christmas Aero' modification gets in the wind tunnel

Tis the season of "Big" - big cheer, big parties, big bowls of eggnog, big decorations, and when it comes to your family hauler, big drag. Festive drivers who festoon their crossovers, minivans, and SUVs with wreaths, Rudolph noses, fuzzy antlers, and rooftop Christmas trees undo the years of work that car engineers devote to fractional gains in fuel economy. To put numbers to such fuel-guzzling madness, GMC started with a 2018 Acadia, optioned it with the Xmas Aero Package - both Standard and Plus versions - put it in Lockheed-Martin's wind tunnel. The resulting dip in fuel economy results probably won't surprise anyone who's used a roof rack - or, for that matter, their car's air conditioning. However, it might surprise you to find out which seemingly substantial decoration had no effect, and which seemingly innocuous decoration was about twice as bad as running the A/C on its Mr. Freeze setting. Check out the brief video above for the results. And consider placement of that bow carefully.

5 classic trucks and their polarizing modern revivals

EVs are helping eliminate Detroit's gas-guzzling problem. Some revivals of gas-powered classics are getting the EV treatment.  But not every revived model looks exactly like its original counterpart. We're in a new era of hulking Detroit metal, and you can thank EVs. Americans can't get enough of their big, beefy trucks and SUVs. But for many years, some of the biggest gas guzzlers fell out of fashion as gas prices rose and emissions regulations tightened. But in the past few years, some of the most iconic American truck nameplates have been brought back to life with electric motors, like the GMC Hummer. In other cases, as with the Ford Bronco, improvements in engine technology and more interest in rugged adventure vehicles made a gas-powered revival possible. Even some revivals that started as gas-powered, like the Chevy Blazer and the Jeep Wagoneer, are now getting electrified spinoffs. (Even if they don't always look quite as sleek as their original inspiration.) Here are side-by-sides of five classic American trucks and their modern counterparts. The Jeep Wagoneer 1975 Jeep Wagoneer and 2024 Electric Jeep Wagoneer SStellantis After a long wait, Jeep released its revival of the classic Wagoneer and Grand Wagoneer in 2020. Starting later this year, an electric version of the luxury Jeep SUV will join the Wagoneer lineup. The Chevrolet Blazer A 1973 Chevrolet Blazer and a 2024 Chevrolet Blazer EVGetty Images, General Motors The Chevrolet Blazer was first rebooted in 2019 as a sporty family SUV. The modern Blazer shares zero resemblance to its boxy, off-roading older sibling, but it has still managed to become one of Chevy's more popular SUVs in recent years. The Blazer EV came later, and was one of the first models GM built on its new Ultium battery platform. The Hummer A Hummer H2 and the 2023 Hummer EV pickup truckGetty Images, General Motors Once the poster child for Detroit's big, bad gas guzzlers, the Hummer got new life as an electric pickup truck in 2021. The Ford Bronco A 1971 Ford Bronco and a 2022 Ford BroncoFord Motor Co. After a rouge group of engineers and designers inside Ford spent years trying to breathe life back into the Blue Oval's boxy off-roader, the Ford Bronco was finally resurrected in 2020 amid a rise in popularity for rugged adventure vehicles.

Top horsepower-per-dollar cars in 2017

Bang for the buck. That quasi-scientific statistic is bandied about by motor heads everywhere from classrooms to barrooms, though the truth of the matter is that it's exceedingly complex to measure. A fair performance-per-dollar index would include something like cross-referencing MSRP (Manufacturers Suggested Retail Price) with point-to-point times on a track or driving route, which is obviously hard to do comprehensively. But, for the sheer joy of talking about cars and playing with a big spreadsheet, there's always the horsepower-per-dollar index, which is more straightforward, albeit hilariously flawed. There are vagaries even with this simple formula, of course: MSRP for vehicles can change at a moment's notice, to say nothing of the bottom-line shifting that happens with local deals or showroom negotiation. For this list we're running with the straight MSRP wherever possible, and as recently reported as we can get it. All the vehicles on this list are 2017 models, and all trims are reported where the lowest price and differing power levels intersect. Some choices were made for personal preference and some for sanity, avoiding things like all 48 trim levels of the Ford Transit, all with the same horsepower). If this list were a simple top ten, or even a top fifty, you'd be bored to tears with all the red, white and blue that is represented. Following perfectly with conventional wisdom, American cars really do lead the world where hp/$ is concerned. So, for the sake of variety (and the sheer joy of seeing a minivan 'win' one round of this thing) I've sorted out some top five and bottom five lists for broad power categories. Let's dive in. Less Than 100 Horsepower Okay, okay, this is hardly a category we'll grant you. But we've often tried to click off all the sub-100-hp cars on sale in the US, and making this list gave us an excuse. It also illustrates that none of these smallish vehicles bring cheap horsepower to the table - for that you'll need a motorcycle. The segment-leading Chevy Spark (above) asks just over $139 for each hp, and that Smart Fortwo Electric Drive has hp on sale for about the same price as its very distant family cousin, the Mercedes-Benz SL65 AMG (insert your favorite Smart joke here... we know you want to).
