Chicago Auto Show: The really big reveals from shows past

The 2024 Chicago Auto Show may seem like a shell of its former self, but it still holds the title of the largest consumer auto show in the United States. It didn't get that reputation simply by being efficiently produced or convenient for locals desperate for something to do in February — it earned it over decades of breaking automotive news and powerhouse reveals, eventually earning an informal designation as America's truck show.  2024 may be a down year for Chicago, but let's not forget all of the great things that have come out of it, historically. Here's a look at some of our staff favorites. Bet you didn't know about a few of these cars that were first revealed in the Windy City.    2008 Dodge Challenger SRT-8  I didn't just pick this one as a former Challenger owner, but instead to illustrate just how many cool Chicago debuts we take for granted. Chrysler often chose its home turf to debut new cars, so the few times its unveilings happened elsewhere tend to stick in our minds. The first Challenger SRT-8 was kind of garbage, if we're being honest. I mean, who buys a race-bred, V8-powered muscle car without a limited-slip differential? But the SRT-8 formula evolved over time into something truly special, and what we saw in Chicago was essentially the early version of the Scat Pack, which was ultimately very successful for Dodge. And who would have thought we'd be here, 15 years later, still talking about that debut? And still loving these big Mopars, flaws and all. — Associate Editor Byron Hurd SHO time in Chicago IÂ’ll always have a certain fondness for the return of the Taurus SHO at the 2009 Chicago Auto Show. Chicago has always leaned truck and van heavy for press reveals, but every now and then, as this list illustrates, something spicy would appear. The return of the SHO as a high-powered successor to the original that ran from 1989-1999 gave enthusiasts hope for FordÂ’s performance business, especially for sedans. With a 3.5-liter EcoBoost V6 packing 365 hp, all-wheel drive and five-spoke wheels, the SHO was a nice upgrade from the lower-rung Taurus models. It was a bit more sedate than the original SHOÂ’s Yamaha-sourced V6 that teamed with a five-speed manual transmission, but still a worthy response to the Chrysler 300, Dodge Charger and later the Chevy SS. The SHO — Super High Output — begat things like the Fusion ST and gave Ford solid four-door performance for the rest of the decade.

2019 Mazda CX-9 gets Apple CarPlay, Android Auto, slightly higher price

Now that Mazda finally launched Apple CarPlay and Android Auto in the 2018 Mazda6, the company isn't wasting time proliferating the infotainment upgrade to the rest of the lineup. The next on the list is the 2019 Mazda CX-9 large family crossover SUV. It's standard on Touring, Grand Touring, and Signature trims. But if you choose to go with the most affordable Sport trim, it's an option. Up-to-date infotainment isn't the only upgrade to the new CX-9. Every version receives thicker floor mats and a thicker headliner meant to further reduce the amount of noise that enters the cabin. The transmission is also retuned, and Mazda says the new tuning is meant to provide a smoother, quieter driving experience. We'll be interested to see how effective it is the next time we have a CX-9 in the office. Each individual trim level also gets some new options and features. The base Sport trim has a Sport Package available that adds heated front seats, a power driver's seat, heated mirrors, lane-keep assist and departure warning, adaptive cruise control and automatic emergency braking. The package rings in at $1,290. The Touring trim gets the fewest new features with its only new addition, besides the infotainment, being a frameless rearview mirror. The Grand Touring trim receives the 7-inch screen in the instrument panel also found in the Mazda6, along with new power side mirrors and a 360-degree camera system. The top-level Signature trim gets new badges, rosewood interior trim, and accent lighting in the grille and around the shifter. With all these new features come new prices, which are naturally higher than last year's. The smallest price increase is between base Sport models. The new one is just $150 more than the old one. The largest increase comes with the Signature trim, which now costs $1,050 more than the 2018 model. You can see the entire price list and changes below. Trim 2019 2018 Sport (FWD) $33,275 $33,125 Touring (FWD) $36,325 $35,955 Grand Touring (FWD) $41,835 $41,465 Signature (AWD-only) $46,360 $45,310 AWD Option (Sport-Grand Touring) $1,800 $1,800 Related Video:

How Mazda got Skyactiv-X to work is incredible

"Take everything you know about engines and turn it around," Mazda North America Vehicle Development Engineer Dave Coleman says, patiently and with a look of benevolent pity, as he's quizzed about the particulars of the company's new engine. The Skyactiv-X engine is enigmatic — and deceptively simple in operation. And the bottom line for American consumers is that they'll be able to buy a car (or crossover; we don't know yet what vehicle will first get it) by late 2019 that provides diesel-like fuel economy but runs on regular old gasoline. In between diesel and spark ignition, but it's neither To truly understand it, you have to dive into the contradictions. Take that regular old gasoline: Contrary to common sense, the lower the octane, the better it works. In the lab, the Skyactiv-X engine loves 80 octane. The lowest Americans get is 87, so the engine is tuned for that octane. Go higher and you lose some low-end torque. Coleman was right. It's hard to wrap your head around an engine that thrives just at the point when most gas engines would aggressively self-destruct. It uses a supercharger to pump additional air — but not additional fuel. It uses spark plugs to start a combustion cycle that normally doesn't need a spark. And, quixotically, it's not displacing Mazda's own American-market diesel engine, currently languishing in a seemingly endless hell of regulatory approval. More bizarre: Mazda is a tiny automaker facing real existential headwinds, and gasoline compression ignition is a massive challenge. GM and Hyundai announced compression ignition, or HCCI, projects (full name, homogeneous charge compression ignition) to great fanfare, but they never amounted to a production hill of beans, crippled by reliability issues or horrible vibrations. Worse, they only worked at an unusably narrow range — low RPMs and low loads. HCCI research improved direct-injection gas and diesel engine technologies for these companies, but HCCI itself remains untamed. The benefits of lean combustion Why even try to tame HCCI? The answer is much better fuel economy and lower emissions. Less burned carbon-based fuel, less carbon dioxide released. That's simple. But there are some thermodynamic reasons for the lean combustion you can achieve with compression ignition that are worth explaining. The ideal amount of fuel for a conventional engine to burn is about a 14:1 air-to-fuel ratio. That lets every molecule burn nicely, in theory.
