Most readers of this site know exactly what an octane rating is and how it relates to the bang it provides in an engine. Hauling up to the pumps and being presented with a choice of everything from 87 to race gas is one of the benefits of living in America.

Higher octane fuel is more expensive than other grades and the gulf between regular and super-duper-extra premium is steadily increasing. Is it worth “treating” your car to a tank of high octane every now and then? The American Automobile Association says absolutely not — and they have the testing to back it up.

General Motors has recently filed a patent that could point to the future of the company’s high-performance offerings, including the C8 Corvette.

After 18 months in review by the United States Patent and Trademark Office, documents published on October 24, 2017, reveal GM has been granted a patent for an internal combustion engine with elevated compression ratio and multi-stage boosting.

The document describes a propulsion system made up of a high compression internal combustion engine that uses a low-flow supercharger in combination with a high-flow turbocharger, linked to “one or more electric motor/generators.”

It gives us an interesting look at how GM engineers plan to continue producing obscene performance cars like the Corvette ZR1 and Camaro ZL1 1LE in a world of increasingly stringent emission regulations.  Read More >

Tuesday morning, as a fresh dumping of snow blanketed your author’s region, we discussed a crucial (and obvious) ingredient for safe winter driving: winter tires.

Far less crucial for day-to-day safety, though still valuable, is another automotive feature — one that regularly sees new car buyers slap down several thousand dollars extra at the dealer. In many cases, the feature immediately goes to drivers’ heads, instilling them with a foolish overconfidence in their vehicle’s mastery of the laws of physics.

We’re talking about all-wheel drive/four-wheel drive. Read More >

It’s no secret that the American buying public shuns four door sedans as if they were an especially virulent leper. Through the first 11 months of this year, the segment is off by over 300,000 units. Almost every car is down, even the spanking-new Honda Accord and Toyota Camry.

Reuters now reports that three of its sources claim Ford plans to consolidate global production of midsize sedans in 2020. The cars will be built in China and shipped to the United States and Europe.

Audi CEO Rupert Stadler has announced his company will dismantle the task force assigned to investigate how many of its diesel cars came equipped with defeat devices. The company established the team after Volkswagen Group admitted to selling 11 million diesel models, through its various brands, with illegal engine management software that hid peak NOx emissions during testing.

Even though Volkswagen has found itself smack-dab in the center of another costly controversy, Stadler claims that Audi is on the cusp of wrapping up its own diesel crisis. “We will have documented and processed all the engine/transmission combinations by the end of the first quarter 2018,” the CEO told journalists at Audi’s headquarters in Ingolstadt, Germany, this week.  Read More >

Despite a surplus of cities seeking ways to reduce air pollution, electric buses haven’t taken off in the United States as expected. While analysts still anticipate a sudden surge in electrification in the years to come, present-day transit authorities have continued opting for dirty diesels as the primary method of moving urbanites around town.

The primary hurdles are infrastructure and cost. Whereas subway tunnels come with equipped with a third-rail ready to deliver the voltage necessary for mass transit, above-ground applications abandoned wire networks the second the trolley fell out of fashion. Electric buses don’t need either, but they do require reliable charging infrastructure and a larger-than-average initial investment.  Read More >

Volkswagen, most recently seen lecturing European governments on the need to ditch the diesel subsidies that, until recently, made it the continent’s most popular fuel, has a bad case of timing.

Just a day after Volkswagen Group CEO Matthias Müller not-so-subtly touted his company’s newfound green bona fides, telling a German newspaper, “We should question the logic and purpose of diesel subsidies,” another diesel-related scandal broke. On Tuesday, Germany’s automobile regulator, KBA, issued a recall of VW’s top-end diesel SUVs.

The reason? Undeclared defeat devices, apparently designed to make the late-model 3.0-liter vehicles run cleaner while undergoing emissions testing. If this doesn’t sound familiar, you’ve been dead for the past two years. Read More >

Compared to the rest of the United States, California is on the bleeding edge of government-appointed environmentalism. When the Trump administration suggested reexamining Obama-era fuel economy and emissions standards, The Golden State was the first to complain, saying it would not be adjusting its goals just because the rest of the country may. It also has pretty serious mandate on zero-emission vehicles — one that forces 15 percent of all new vehicles sold in the state to use zero-emission powertrains by 2025.

While California isn’t alone — nine other states have followed its lead since Trump took office — it is the keystone star on America’s flag pushing to maintain expand fuel regulations. Automakers have noticed and, despite previously having agreed with President Obama’s emission standards several years back, they’re launching a counter-offensive.

Arguing before a U.S. House panel, the Association of Global Automakers complained that California’s ZEV mandate threatens a single national standard for fuel economy. Read More >

Arrogance (noun): the quality of being over-confident; synonyms: conceit, egotism, attitude of Range Rover Velar sales team.

That’s not trademark TTAC snark, either. Take it from Andy Goss, the company’s global sales operations director, who said its UK dealers were “probably a bit complacent” about the Velar and its chance for success.

Officially, there is no word. Unofficially, Acura seems plenty content with the idea of bringing the Chinese-market CDX subcompact crossover to North America, so long as there’s a business case for it.

“It’s a model that interests a lot of our people, so we have our R&D guys looking into the possibility,” said Jon Ikeda, vice president of American Honda’s Acura division, last April.

Is an American design patent granted to Honda proof that the company’s braintrust have made up their minds? Read More >

Earlier this week in TTAC’s always entertaining Slack chat, Adam Tonge suggested (without sarcasm) how the B&B might enjoy discussing the market entrants of the Diamond-Star Motors company and picking favorites. Shortly after this discussion, the very DSM Plymouth Laser we saw in yesterday’s Rare Rides fell right in my lap, and this all seemed like destiny.

Of the varied selection, which Diamond-Star Motors vehicle is your favorite?

In 1990, the Nintendo Game Boy was flying off store shelves, neon clothes was very much in vogue, and President Bush was busy denouncing broccoli. And — oh, yeah — Honda rolled out a new Accord for the 1990 model year.

With a strong visual presence giving it a refined and contemporary look, the Accord Coupe made the best of its expansive greenhouse and flush-fitting glass. Before you protest, I know the above Accord is not a DX … but the one after the jump is. I think it’s fabulous and I know you do, too.

Back in 2015, Volvo Cars reiterated that it would test hundreds of autonomous vehicles in the United Kingdom, Sweden, and China by 2018 as part of its Drive Me project. Using cars equipped with advanced autonomous technology, the initiative hoped to help Volvo understand how customers interact with self-driving cars.

However, the automaker appears to have tweaked that plan in a recent press release. Instead of families helping Volvo test new autonomous vehicles, they’ll help develop them by cruising around in well-equipped XC90s. While we can’t cry foul too loudly, Volvo has used highly suggestive language for the last few years. It previously claimed it would have “death-proof” cars on the road by 2020 and alluded to Drive Me using fully autonomous test vehicles — not commercially available models.  Read More >

You’ve decided to take the plunge. To lay down significant cash for a personal vehicle that burns no gasoline and isn’t a bicycle. Unlike the plethora of dino juice-sipping models competing for your attention, your choice of electric vehicles is still modest, albeit growing, and comes with a list of ownership concerns never mentioned around traditional cars.

Range, charging times, home connections, and the impact of temperature on the battery pack (and its longevity) are just some of the questions a salesman might be asked about. Pricing is easy.

This past fall, research firm Ipsos RDA Automotive sent secret shoppers into 141 EV-selling dealerships in the U.S., where the spies feigned interest in purchasing one of 11 fully electric models. The experience was a wildly mixed bag. It’s not entirely surprising, but in many showrooms dominated by gas-powered cars and SUVs, the sale the dealer employee attempted to close was not for the EV the secret shopper came in to buy.  Read More >

Florida lawmakers are pushing a new bill that would make it illegal to have your car stolen if you haven’t bothered to take the keys out of the ignition. While accidentally prepping a car for prospective thieves is easily one of the dumbest things you can do, making it illegal to leave it running while you pop in to buy a pack of gum sets us up for a nice slippery slope argument.

Last week, State Representative Wengay Newton and Senator Perry Thurston introduced matching proposals (House Bill 927 and Senate Bill 1112) that would make leaving your car unattended without stopping the engine, locking the ignition, and removing the key a second-degree misdemeanor. Under the Florida statute, the crime would be punishable with a $500 fine and up to 60 days in jail.
