With front-wheel drive, a 2.0-liter turbocharged four-cylinder engine, and a seven-speed dual-clutch transmission, the all-new 2017 Audi A4 Ultra’s EPA highway fuel economy figure is 37 miles per gallon.
Audi says, “No other luxury sedan in its competitive segment offers higher EPA-estimated city or highway mileage” than the new fuel-sipping A4, which the Environmental Protection Agency rates at 27 mpg in the city and 31 mpg combined.
The EPA scores the rear-wheel-drive BMW at 32 mpg city and 42 highway and the 330e at a combined 72 mpge equivalent. Audi presumably excluded these non-entry-level, uniquely powered models from the “competitive segment” definition. (Read More…)
Infiniti has a revolutionary new engine in the works that’s both a high-compression mileage-maker and a low-compression pavement burner, giving drivers the option of being lean or mean at any given time.
The world’s first variable compression engine, dubbed the VC-T, ate up 20 years of design work before Infiniti went public with its achievement. The automaker plans to unveil the revolutionary engine next month, at the Paris Auto Show. (Read More…)
The search for better fuel economy takes engineers down weird paths, and the latest plan to wring out extra mileage is no different. It involves an unlikely part of the vehicle — the suspension.
Audi just announced a new suspension system that harvests wasted energy and turns it into electricity, capable of adding juice to a vehicle’s 48-volt electrical subsystem. (Read More…)
The dialogue from Tesla wasn’t all rainbows and puppies this week.
In oddly coordinated diatribes, CEO Elon Musk and his vice-president of business development took off the soft driving gloves and laid into their competition and the country’s regulators. The message? Put up, pay up, or shut up. (Read More…)
After scoring a stellar deal on our ’15 Ford Fiesta 1.0 EcoBoost, thanks to the advice of those who know more about the car buying process than I do, my girlfriend and I have put just over 3,000 miles on our diminutive hatchback.
In those 3,000 miles, the Fiesta has patiently allowed Jenn to hone her manual-transmission skills, been to the dealer once (more on that in a bit), carted us and our furry dependents around the province, and not once been close to an autocross course — though not due to my lack of trying.
The federal agencies reviewing the country’s corporate average fuel economy (CAFE) targets are pleasantly surprised by the amount of fuel-saving technology in modern vehicles, and hint that the target they decided on back in 2011 is still doable.
Those agencies just released a technical assessment report (TAR) to guide the review process. In it, they figured that vehicles will average between 50 and 52.6 miles per gallon by the target year of 2025 — if gas stays stable and consumers continue buying SUVs and trucks.
That’s not too far off the original target, and judging by the optimistic tone of the report, it’s likely the 54.5 mpg mandate will stay intact. (Read More…)
Business is about to get much more expensive for automakers with thirsty fleets.
The penalties leveled by the National Highway Traffic Safety Administration against automakers who miss their annual corporate average fuel economy (CAFE) standards are about to go up in August. Way up. (Read More…)

My cars from the early 2000s had automatic transmissions that seemed to allow freewheeling when you lifted off the pedal. I used this for better gas mileage by letting the car coast when I could see red lights far ahead.
Starting about 2010, my cars produced by GM began acting more like their standard transmission counterparts by employing engine braking and downshifting as they came to a stop. This works great in mountain driving where engine braking is needed, but wouldn’t freewheeling on flatter ground allow better gas mileage?
A group of automakers wants Big MPG to know they’re out of touch when it comes to fuel efficiency targets, and would really like it if they stopped paying so much attention to California.
The Alliance of Automobile Manufacturers — a Washington lobbying group made up of General Motors, Ford, Fiat Chrysler Automobiles, Volkswagen and Toyota — wants to impact the midterm review of 2025 fuel economy targets set in 2011, Bloomberg reports. (Read More…)
