2015 Subaru WRX: Road trip to Maine [w/video]

After driving one of the best sport compacts on the market to one of the best-driving-roads states in the Union, who'd have thought that one of my big takeaways would be... great fuel economy? And yet, after putting more than 2,200 miles on our long-term 2015 Subaru WRX, driving from Ann Arbor, MI, to The Great State of Maine and back, my overall fuel consumption figures were almost as baffling as the premium-gasoline prices throughout Canada. In the early part of the now-past autumn, my wife Molly and I were happy to make use of the long-term WRX for our annual road trip from Michigan to Maine. Our goal, as ever, was to fit as much hiking, boating and lobster eating as we could into a one-week span. And, with the sporting Scoobie as our ride this time, I also hoped to spend time bombing down some of my favorite roads through the White Mountains. Anyone that pays attention to the industry knows that New England is a hot spot for Subaru sales, but it turns out that the WRX is just about tailor made for enjoying the best of Maine, too. First up, though – as it was the most surprising to me – is the fuel economy story. I knew going into the trip that I'd log more than two grand on the odometer, but I never expected the returns to be quite so positive as they ended up netting out. My total observed economy over 2,226 miles was 28.38 miles per gallon, or just a fraction better than the EPA estimated highway number of 28 mpg. How'd I do that? My total observed economy over 2,226 miles was 28.38 miles per gallon. Well, for starters, the stretch of Canadian highway between Michigan and Vermont is exceptionally long, flat, straight and dull. Excepting the inevitable traffic around Toronto, the trip is mostly of the "set it and forget it" variety, typically at a cruise of about 72 miles per hour (so as not to attract the Mounties). Doing that haul, I had one tank of premium (15.9 gallon capacity) last for 466 miles, running a trip-best 31.9 mpg. Considering that the Canadian petrol was running me roughly five American bucks per gallon, I appreciated the Subie's newfound frugality. One small issue, tangentially related to fuel, did crop up on the road. The WRX's gas door stopped popping open when I pulled the lever after my second fill up. As it turned out, there is a technical service bulletin out for this very issue, which was looked after as soon as we got back to the States.

US Army tests Subaru-powered hybrid truck

The military has been studying the implementation of alternative drivetrains for years, a tiny sampling of which includes the diesel-electric hybrid technical hauler and L-ATV from Oshkosh Defense and the Aggressor from Quantum Technologies. There was also ADA Technologies' work with ultracapitors, General Motors' focus on fuel cells and the roll out of electric motorcycles for Special Forces. In the Ultra Light Vehicle (ULV) prototype vehicle pictured above, we have the latest developments in the Department of Defense's hybrid interest combined with a need to develop a lightweight replacement for the AM General Humvee.
In 2010 the Office of the Secretary of Defense put the Army's Tank Automotive Research, Development, and Engineering Center (TARDEC) in charge of developing a personnel carrier that could "balance payload, performance and protection," and do so without exorbitant cost. Armored Humvees can weigh more than seven tons, and while the ULV is just under 14,000 pounds, the new vehicle can do a lot more with its weight.
The Subaru turbodiesel under the hood puts out 175 horsepower and 260 pound-feet of torque. That's not much for pulling 13,916 pounds, so it's assisted by two Remy 410HVH HT electric motors each capable of adding 268 continuous hp and 369 peak hp, along with 844 lb-ft of continuous torque or 1,221 ft-lbs at peak. They're only limited by the 14.2 kWh lithium-ion battery rated at 65 kW of continuous power and 180 kW of peak power, but still, TARDEC says the ULV can do 21 miles on electric power and on the flats has a combined range of 337 miles at 35 mph.

Subaru WRX and STI meet at the dyno with interesting results

Road and Track recently put the 2015 Subaru WRX and the 2015 WRX STI through a battery of dyno tests to find out not only how much difference there is between their two engines, but what kind of differences there are. The WRX gets the company's new FA20 2.0-liter boxer four-cylinder engine with features like a twin-scroll turbocharger, direct injection and variable valve timing on its two cams. The WRX STI stands pat with the older EJ-Series motor, meaning a 2.5-liter boxer four-cylinder with port fuel injection and carryover turbo lag. Subaru pegs the $26,295 WRX at 268 horsepower, 258 pound-feet of torque and an "extremely conservative" 0-60 mile per hour time of 5.4 seconds. The $34,495 STI clocks in at 305 hp and 290 lb-ft with a 0-60 mph time of 5.1 seconds. Ok, fight.
R&T's dyno runs sussed power numbers at the wheel of 223 hp and 245 lb-ft for the WRX, 247 hp and 243 lb-ft for the STI, then went on to demonstrate in numbers what everyone knew: that the WRX consistently puts out more of its torque earlier than the STI and achieves full boost almost three seconds quicker. On the other hand, on the track, the STI was also shown to have a conservative official 0-60 mph time, stopping the timer at 4.8 seconds compared to the WRX's 5.2 seconds.
The mag says it has comprehensive results coming from its "complete battery of tests," but for now, you can scrutinize their dyno charts and let the battle continue about which one you'd rather put your money down for.
