Just to clear things up right off the bat, Jaguar’s newest model, the E-Pace, is not the brand’s upcoming electric sport crossover. That’s the I-Pace. Because “I” stands for … ions, we presume.

No, the E-pace is the smaller answer to Jag customers looking for something less than an F-Pace, but not too much less. Riding on the Range Rover Evoque platform, the E-Pace boasts less overhang and a shorter overall length, while retaining the styling cues and handling of its popular larger sibling. However, despite being smaller in most dimensions, there’s one area where it actually tops the F-Pace: in consumption of fuel. (Read More…)

When I was in California this week to drive the all-new Kia Stinger, there was one key specification question that went unanswered – fuel economy. That’s because the numbers were being finalized as we sat in the press briefing.

Now we know the numbers, at least by the American standard.

We’ve mused on Infiniti’s Variable Compression Engine in the past, calling it everything from a chameleon to the holy grail. Its killer app? The ability to changes the distance the pistons travel in their cylinders by as much as 6 mm, or about a quarter of an inch.

Why is this important? Because it is, arguably, the first major change to the workings of a internal combustion engine in more than a century.

There’s no confirmation just yet, but all signs are pointing to the eventual introduction of Nissan’s novel e-Power hybrid system in its U.S. lineup.

We say “novel” because the system isn’t like any gas-electric setup currently on the road. Think of it as a way to cheaply reduce emissions without the worries of limited electric range or the expense of bulky battery packs. Instead, think of the car as a little ship. (Read More…)

The program for Jeep’s new Wrangler has had more leaks than a screen door on a submarine, from the leak of its owner’s manual and standard options list to the discovery by our own Bozi Tatarevic of potential power numbers for the JL’s new turbocharged mill.

Always of interest to new-car shoppers are the official fuel economy ratings. Such numbers just appeared for the new Wrangler on the EPA’s website, leaving only the texture on underside of the JL driver’s seat as a surprise for its big reveal at the L.A. Auto Show later this year.

There’s nothing quite as uncertain as that little number staring at you from the window sticker of a new vehicle. It’s two digits long (unless you’re fabulously rich), followed by the word “combined.” We’re talking, of course, about the Environmental Protection Agency’s fuel economy rating, which often turns out to be an impossible-to-reach goal or — if you’re lucky — a lowballed figure.

Back in the days of lapels and flares, the hot gas mileage action was found in the compact and subcompact class. Economy cars, after all. Well, people these days prefer driving a vehicle that seats at least five adults in comfort while towing a boat and hauling 65 pounds of kid’s toys and a dog in the rear cargo area. With the heyday of the cheap little car long gone, the (fuel) economy battle rages anew among the largest, and most lucrative, vehicles on the road.

So, do you believe the EPA when it says the massive 2018 Ford Expedition gets 20 miles per gallon combined? (Read More…)

Think of the Ford F-150 pickup and one’s mind immediately turns to an excellent pair of EcoBoost V6 engines with 2.7 and 3.5 liters of displacement. And why wouldn’t you? Together, Ford’s twin-turbocharged V6 twins make up three-quarters of the model’s engine share. These beauties are the last word in full-size pickup torque, though the 2.7-liter is a wanderer that finds deserving homes in such models as the Ford Edge, Lincoln MKX, and Ford Fusion Sport.

For 2018, both EcoBoost engines see some refinements, but buyers of F-150 XL and XLT pickups won’t see either if they leave those option boxes unchecked. In a bid to increase fuel efficiency across the lineup, 2018 sees the introduction of a naturally aspirated 3.3-liter V6 in low-rung trims, replacing the previous 3.5-liter unit.

There’s no shortage of technology at work with the new 3.3, but it can’t match the fuel economy of the closest available engine upgrade. (Read More…)

Picture a suburban street in an average middle class neighborhood. In each driveway sits two vehicles, as tradition states no modern American suburban family can make do with just one. Think about those two vehicles for a minute now.

Are they evenly matched? In other words, are they the same size? Do they fulfill the same requirements laid out by a single segment? Doubtful, and your mind’s eye already made this clear. One’s a Safari or Caprice wagon, the other’s a Datsun 210. One’s a Corolla, the other, a Suburban. A Focus and an F-150, and so on.

Does owning an economy car compel new car buyers to splurge when new-car buying time rolls around? Logic, and now science, says yes. (Read More…)

A bipartisan pair of congressional representatives from Michigan are proposing a new bill, the Fuel Economy Harmonization Act, that would aid automakers in complying with federal fuel efficiency requirements. Introduced on Wednesday, the bill would extend the life of fuel economy credits that are set to expire in five years and raise the ceiling on transferrable credits between car and truck fleets. Under the proposal, manufacturers could also be given additional credits for lowering fleet-wide emissions under new metrics.

Penning the bill, congresspersons Fred Upton (Republican) and Debbie Dingell (Democrat) said they believed the automotive industry would benefit from having a single set of fuel rules. The bill suggests rolling the NHTSA’s Corporate Average Fuel Economy (CAFE) and the EPA’s light-duty vehicle Greenhouse Gas Emissions mandates into one cohesive program.

While economy mandates have been growing, nationwide fuel consumption has still gone up. Likewise, the average mpg of cars sold in the United States hasn’t changed much over the last three years. With pump prices remaining low, consumers have flocked to less-efficient models like crossovers and SUVs.  (Read More…)

Those Ford Mustang owners. Obsessed with just one thing — a feverish, burning desire to consume as little gasoline as possible.

No, that can’t be right. Mustang buyers know what they want when purchasing the original pony car, and it usually involves the velocity of wind through one’s hair. Ford Motor Company, however, doesn’t have the luxury of such simple-mindedness. For a number of reasons, the largest of them being regulatory, the automaker requires its newest vehicles to burn less fuel than the previous generation.

The 2018 Mustang is no different. For the coming model year, the massaged and freshened Mustang promises owners less time spent at the gas pump. (Read More…)

As Fiat Chrysler’s Ram division enjoys wearing the full-size pickup fuel economy crown with its now-legal-again 1500 EcoDiesel, and as Ford throws turbo V6s and 10-speed automatics at everything, what’s General Motors supposed to do to greenwash its truck fleet?

Easy. Simply offer customers in all 50 states a rare option previously available only in California. (Read More…)

From a historical midsize perspective, the all-new 2018 Honda Accord is rather thrifty with the Earth’s decreasing supply of oil.

It’s fuel efficient, in other words. Over the span of 10,000 highway miles, the basic 2018 Honda Accord is expected to consume 263 gallons of regular octane gasoline. That’s only 13 more gallons than you’ll consume in a 2018 Honda Civic Hatchback with the same 1.5-liter turbocharged four-cylinder. It’s 15 fewer gallons than you’d have used in the most efficient non-hybrid 2017 Honda Accord.

The city improvement is more meaningful. The 2017 Honda Accord four-cylinder topped out at 27 mpg in the city, equal to $944 for 10,000 miles at the current fuel price of $2.55/gallon. The new 30-mpg Accord reduces city consumption in the same scenario to $850, a 10-percent decrease.

The 2018 Honda Accord is not, however, the most fuel-efficient car in America’s midsize sedan category. Honda thought it would be. Honda was wrong. (Read More…)

Say you’re on the Ram website, perusing a new 2500 heavy-duty pickup. On the specifications page, you scroll down to the fuel efficiency table to see how many Andrew Jacksons you’ll be forking over at the pumps. The verdict? The Ram 2500 has a 32-gallon fuel tank. Thank you for visiting.

Unlike passenger cars and light duty trucks, heavy-duty trucks with a gross vehicle weight above 8,500 pounds aren’t required to flash fuel economy data on a window sticker. Searching the fueleconomy.gov database turns up nothing in the way of information. Now, Consumers Union wants Congress to change that. The consumer advocacy group is calling on the federal government to place fuel economy information on window stickers for the benefit of large truck buyers.

As it awaits a response, the group’s Consumer Reports publication went ahead and tested some heavy-duty pickups. (Read More…)

At launch, the lone Volkswagen Atlas available in the United States was the more powerful 3.6-liter V6, a Tennessee-built $34,425 three-row crossover with 276 horsepower and 266 lb-ft of torque. All-wheel drive is an $1,800 option. The Atlas was rated at 18 miles per gallon in the city; 25 on the highway. City fuel economy for AWD models dropped by a single mpg; highway mpg fell to 23.

Now we know how much money you can save by purchasing the front-wheel-drive-only Volkswagen Atlas 2.0T, which suffers a loss of 41 horsepower but generates very nearly as much torque as the V6 (258 lb-ft) and does so 1,150-rpm closer to idle.

Not surprisingly, a small, modern, turbocharged engine is barely more efficient than the larger, naturally aspirated V6. (Read More…)

A handful of states have banded together to sue the Trump Administration for delaying financial penalties associated with automakers’ inability to meet minimum fuel economy standards. As part of the president’s deregulation proposals, the National Highway Traffic Safety Administration has placed Obama-era mandates on review as regulators debate whether to grant automakers significant reductions in fuel economy requirements.

However, those changes have yet to arrive, meaning the industry is still under pre-existing standards — and some states want automakers held accountable. California, New York, Vermont, Maryland, and Pennsylvania want the current administration to introduce its proposed quotas or enforce the already established 2016 limits.  (Read More…)
