The tricky business of octane, power, and MPG

Given tepid green-car sales numbers this year, consumers in the US aren't making the transition away from internal combustion engines too quickly. Regulations are still mandating cleaner emissions, though. In addition to downsizing and turbocharging, there's growing consideration about moving to higher-octane fuel to improve overall efficiency. In a new report, engineers at FCA, Ford and General Motors Powertrain are showing that it could work, too. The major advantage to higher-octane fuel is that it supports higher compression ratios. That in turn can lead to more power from burning the same amount of gas. "Higher ethanol content is one available option for increasing the octane ratings of gasoline and would provide additional engine efficiency benefits for part and full load operation," the researchers write in the study's abstract. The authors even think it could be possible to update some modern vehicles' engine calibration to be optimized for the better gas. While the benefits are there, we still have a long way to go before higher-octane fuel becomes a national standard. According to Green Car Congress, 87 percent of the gas sold in the US is regular grade 87-octane. Meanwhile, premium 91-93 octane makes up just 10 percent. The various grades of fuel illuminate even more annoyances with the current system. For example, Ford generally recommends 93-octane for EcoBoost engines, and the power outputs that the company publishes are based on using it. However according to Green Car Reports, such premium gas is very difficult to find in some regions of the US, especially along the West Coast. The powertrains still run on lesser grades but with lower power output. The researchers' discussion of possibly increasing ethanol in gas also comes during a heated debate on the substance. The current administration is pushing for less of the corn-based fuel in the coming years. Although, several presidential hopefuls might be favor of reversing that course.

Junkyard Gem: 1973 Mercury Marquis Brougham 4-Door Pillared Hardtop

Ford's Mercury Division debuted the Marquis in the 1967 model year, as a sporty coupe based on a stretched Ford LTD chassis. When the LTD got an update for 1969, so did the Marquis, and production of that generation of the top-of-the-line Mercury continued through 1978 (the Grand Marquis hit streets the following year). The 1969-1978 Marquis was a big, imposing land yacht, and the Brougham version came absolutely loaded with affordable luxury. Today's Junkyard Gem is a Marquis Brougham from the first year of the Malaise Era, found in a Phoenix self-service car graveyard recently. This car appears to have spent decades sitting outdoors in one of the harshest climates in the country, and so it's in rough shape. The vinyl top received the full thermonuclear treatment and is mostly obliterated by now. The interior got thoroughly cooked as well. Still, its original opulence shines through if you use some imagination. What hurts is that this car was packed with most of the good options, including the mighty 460-cubic-inch (7.5-liter) V8 engine with four-barrel carburetor. The price for the 460 was just $76 in this car, or around $548 in today's money. The base engine was a 429 (7.0-liter). Power numbers were way down for 1973 when compared to a couple of years earlier, partly as the result of tightening emissions standards but mostly due to the switch from gross to net power ratings that began midway during 1971 and was completed by the end of 1972. This engine was rated at 202 horsepower and 330 pound-feet. The only transmission available was a three-speed automatic. We can assume that the original buyer of this car and its single-digit fuel economy had a rough time when the OPEC oil embargo hit in the fall of 1973. Believe it or not, air conditioning was not standard equipment on the '73 Marquis Brougham (you had to move up to a Lincoln for that). This one even has the automatic temperature control feature, adding a total of $508 to the cost of this car (about $3,661 in 2023 dollars). That AM/FM/8-track radio—or, in fact, any radio—was an extra-cost option as well, with a price tag of $363 ($2,616 after inflation). The MSRP for the 1973 Marquis Brougham sedan (known as a "pillared hardtop" thanks to the frameless window glass) was $5,072, which comes to $36,555 in today's dollars. Obviously, its out-the-door cost would have been much higher with all the options.

'84 MotorWeek Cherokee, Bronco and Blazer comparison indulges your SUV nostalgia

These days, truck-based, full-frame SUVs are somewhat of a rarity on the auto landscape due to the rapid rise in popularity of easier-driving, car-based crossovers. Although, without the gradually building popularity of these chunky, high-riding vehicles decades ago, it's unlikely that America's roads would be filled with so many CUVs today. In its latest dig into the archives, MotorWeek has found a 1984 comparison test of a trio of these early Sport Utility Wagons, as long-time host John Davis called them, that helped get acceptance of this segment going. This is a red, white and blue test of the SUVs from American automakers at the time and pits the Chevrolet Blazer, Ford Bronco and Jeep Cherokee (specifically in Wagoneer guise) against each other. Driving manners and interior usability are considered in the evaluation, but Motorweek actually takes these vehicles off road, too. Among the bigger revelations is the improvement in on-road ability in the past 30 years. While specific 0-60 times aren't given, all three models take around 10 seconds just to get to around 50 miles per hour in the 500-feet on-ramp acceleration test. Check out this clip to see just how far this segment has progressed in the past three decades or just get a blast of nostalgia from these now vintage models.
