EPA says fuel economy test for hybrids is accurate

The EPA says it stands behind its fuel economy test for hybrid vehicles following controversy about the testing process after Ford C-Max Hybrid customers and automotive journalists alike struggled to achieve 47 miles per gallon, the advertised mpg number, Automotive News reports. Ford responded to the issue almost two weeks ago by claiming that a 1970s-era EPA general label rule was responsible for the inaccurate mileage numbers, rerating the C-Max Hybrid's mpg numbers and offering customers rebates. Ford later said it didn't overstate the C-Max Hybrid's fuel economy and that it was surprised by the low numbers.
Ford technically didn't do anything wrong because it was following the general label rule, but agency regulator Christopher Grundler says the automaker was exploiting a loophole when it came up with the hybrid C-Max numbers, and that the testing process remains accurate. The general label rule allows vehicles that use the same engine and transmission and are in the same weight class to share fuel economy numbers, but it doesn't take into account other factors such as aerodynamic efficiency, which affects hybrids more drastically than non-hybrid vehicles. Ford originally used the Fusion Hybrid economy figures for the C-Max Hybrid and claimed the engineers didn't realize that its aerodynamic efficiency would affect fuel economy as much as it did.

Road tripping in a Ford Fusion Energi PHEV

Following my earlier Chevy Cruze Diesel trip and recent press-launch drives of Volvo XC90 and Hyundai Sonata plug-in hybrids, an opportunity arose for another road trip. I wanted to do it in a plug-in hybrid, primarily to learn whether its higher price vs. gas-powered and conventional hybrid versions of the same vehicle – is justified by its capability to operate as an EV, burning no fuel at all with its engine off, at least for short distances. I've been skeptical of plug-in parallel hybrids. As I've written before, I've been skeptical of plug-in parallel hybrids because they are generally good for very limited electric miles (typically 10-15, depending on driving style, terrain, and temperature) at fairly leisurely speeds before their engines kick in. But I've recently spent time in two new examples – the 2016 Volvo XC90 T8 and the 2016 Hyundai Sonata PHEV – that offer more EV range, mostly because they tote bigger (thus more expensive) batteries. Both promise 24-25 miles of battery-only range, and the latter can recharge on the fly. Unfortunately, neither was yet available for my July road trip, nor was a Honda or Toyota plug-in, but Ford anted up a Fusion Energi borrowed from its Marketing department. "The state-of-the-art lithium-ion battery and electric motor combined with the gasoline engine offers maximum efficiency," says Ford about it. "This strategy offers the best of both worlds, providing the 2016 Ford Fusion Energi the capability to be driven as an electric vehicle for short trips and as a hybrid for longer trips." I've been a fan of Ford's Fusion since the first-generation debuted a decade back, and the handsome Gen II version launched for 2013 has been Detroit's best answer to the Honda Accord/Toyota Camry/Nissan Altima Japanese juggernaut in the popular US mid-size sedan segment. Beyond its leading-man looks, it offers an array of highly-functional features (some exclusive), a choice of three gas engines (a base 2.5-liter four and 1.6-liter and 2.0-liter direct-injected, turbocharged EcoBoost fours) and both parallel and plug-in parallel hybrid versions. The regular hybrid originally boasted 47 mpg before Ford adjusted it to be more realistic. The gas engines drive through a 6-speed automatic transmission (a 6-speed manual is standard with the 1.6-liter EcoBoost), the hybrids through an electric continuously variable transaxle (eCVT), and all-wheel drive is available with the 2.0-liter EcoBoost four.

This Ford F-150 might have a Land Rover turbodiesel V6

Our spy photographers just caught this Ford F-150 driving around Dearborn, wearing camouflage around the bed – not so unusual near Ford's headquarters. What's interesting with this particular mule is that it might be packing a Jaguar-Land Rover turbodiesel V6. As with the Super Duty, the F-150 prototype pictured here sports a Venturi exhaust tip popping out the side of the rear bumper behind the wheel, which – along with the sound reported by our shutterbug – suggests that it's burning oil up front. That could mean Ford has found another application for the 3.2-liter, five-cylinder Power Stroke diesel that it just federalized for the Transit van. However our sources suggest what the mule is actually powered by the 3.0-liter Lion V6 diesel that Jaguar Land Rover – once subsidiaries in Ford's Premier Automotive Group – is bringing over for the Td6 models of the Range Rover and Range Rover Sport. The engine produces a respectable 254 horsepower and a healthy 443 pound-feet of torque, and is tipped to be mated to the same ten-speed automatic transmission as the new Raptor. That could give the F-150 the kind of fuel economy and muscle it would need to challenge the likes of the Ram 1500 EcoDiesel and the heavier-duty Nissan Titan with the Cummins engine. With gas prices as low as they are, however, and sales of diesel-powered vehicles lagging, Ford could just be trying to keep up with the competition by offering a light-duty diesel pickup. With its lightweight aluminum body, the diesel F-150 could even surpass the Duramax diesel-powered Chevy Colorado and GMC Canyon for frugality at the pumps, according to Mark Williams of PickupTrucks.com. He told Autoblog that, "it makes perfect sense for Ford to do a diesel. It seems like everyone is pushing them to do a Ranger, but if they can get the F-150 to push 30 mpg it can challenge the Ram Ecodiesel and even the Colorado Duramax." Reached for comment, Ford spokesman Mike Levine sent us the following statement: "We do not speculate about future products. While diesel is a solution, it is not the solution. EcoBoost offers the ideal combination of performance and fuel economy that over 60 percent of F-150 customers are choosing."
