Yep, it's almost the end of the year, which means reams of roundup stories from all your favorite auto websites. Nope, we're not that different: We've got one too. Here's our take on the five most important stories--or perhaps themes--of 2011 in the growing world of green cars.
New fuel economy rules: 54.5 mpg CAFE by 2025
The biggest story of the year is the new gas-mileage requirements jointly issued by the NHTSA and EPA--under the encouragement of the Obama White House, and with signoff from most if not all of the major automakers. (Auto dealers are still fighting the rules.)
The new corporate average fuel economy (CAFE) rules cover model years 2017 through 2025, and include rises of 3 percent per year for trucks and 5 percent for cars.
The result is that by 2025, the average vehicle will achieve 54.5 miles per gallon on its CAFE tests--which translates to the low to mid 40s on a new-car window sticker (due to outdated CAFE test cycles).
How will we get there? Sure, there'll be more hybrids and some plug-in cars. But the vast majority of the increased gas mileage will come from smaller, more efficient engines.
We're already seeing this, with four-cylinder engines becoming the de facto standard--neither the Hyundai Sonata mid-size sedan nor the 2013 Ford Escape compact crossover will offer a V-6--and V-8s being relegated to trucks and low-production sports cars like the Camaro and Mustang.
Even pickup trucks now come increasingly with V-6 engines. Just four months after Ford offered a 3.5-liter Ecoboost direct-injected and turbocharged V-6 in its F-Series pickups, that engine was racking up one-third of all F-Series sales.
A year after its launch, more Ford F-Series trucks are now sold with V-6s than with V-8s--which hasn't happened since 1985. As of yesterday, Ford said it had sold more than 100,000 EcoBoost direct-injected and turbocharged V-6 engines in F-Series pickups during 2011.
