2007 Subaru Impreza Performance
This performance review was written when the 2007 Subaru Impreza was new.
All 2007 Subaru Impreza models have all-wheel drive, a popular feature among auto reviewers and cold weather drivers, in particular. However, Car and Driver notes (of the non-WRX Imprezas), "if this is an honest, no-frills piece of engaging engineering, it is also showing its age."
Cars.com specifically notes the Impreza's ability to accelerate. "The Impreza WRX looks the part of a hot performer and delivers the goods, too." Motor Week likes handling on corners, recollecting, "a simple lift of the gas pedal, and the back end drifts gently out, giving you a nice straight line out of the corner and allowing you to put the power down early."
Acceleration and Power
The 2007 Subaru Impreza's 2.5i features a 2.5-liter SOHC aluminum-alloy 16-valve Subaru boxer engine, while the WRX and WRX TR have 2.5-liter DOHC intercooled boxer engines. Kelley Blue Book finds that either engine "performs as smoothly as any in-line four-cylinder mode," while Automobile.com's reviewer reveals, "I love the sound of the boxer engine. It's kind of like a muted VW bug." Auto writers note problems as well. Consumer Guide says the WRX "can feel lazy, slow to react to throttle below 3000 rpm," and the doesn't enjoy "vibration that came through nearly all the time."
All models have a five-speed manual transmission but the option for a four-speed automatic transmission. Car and Driver makes a list of worries about the WRX. Starting with a clutch take-up that is "slightly abrupt, making smooth launches tricky," the reviewer goes on to relate too much transmission wind-up and then concludes with, "there is substantial wind noise at speed" and "the cruise control can't be set above 92 mph."
When testing the base model Impreza's fuel economy with a five-speed manual transmission, the Environmental Protection Agency estimates18 miles per gallon in the city, 25 on the highway, using premium gasoline, 19 miles per gallon city and 26 on the highway with regular gasoline. When testing the six-speed manual, the EPA rates the Subaru Impreza at 17 miles per gallon on city streets, 23 miles per gallon for the highway using premium gasoline. With the automatic transmission, the EPA rates the Impreza at 18 miles per gallon in the city, 23 miles per gallon on highways, when using premium gasoline. Using regular gasoline, the EPA rates the Impreza at 20 mpg city/25 mpg highway. Although few reviewers mention the 2007 Subaru Impreza's fuel efficiency, Consumer Guide tested the 2.5i and the WRX to find "2.5i averaged 20.5 mpg in mostly city driving. In city/highway driving, test WRX sedan averaged 24 mpg."
Handling and Braking
The 2.5i, WRX and WRX TR models of the 2007 Subaru Impreza all rely on a sport-tuned four-wheel independent suspension with strut front and rear suspension, which the Edmunds says WRX and 2.5i feel "very secure" thanks to their "well-tuned" suspension, and adds that the 2.5i is "enjoyable to toss around on a twisty road." The also enjoys the Impreza's good handling, writing that the "steering is quick and the ride is firm but supple."says manages the Impreza's "motions stably and allowed for sporty handling without being overly aggressive."
To stop the 2007 Subaru Impreza, all models call on four-wheel disc, ventilated front brakes with dual-piston front and single-piston rear calipers, as well as four-channel, four sensor anti-lock brakes with Electronic Brake force Distribution standard. Several auto writers chime in on the quality of the Impreza's brakes, regardless of trim. As Auto Mall USA relays about the WRX brakes, "it's more than impressive stopping power. The ABS is tuned in outstanding fashion. Try a panic stop on those battle-scared roads and the WRX stops like a champ (and it is, in the World Rally Championship), without losing composure, even if you are turning at the same time." The notes that any of the trims brakes "produced pleasingly short stops time after time from elevated velocities, with good pedal feel. The anti-lock purred rather loudly when I forced it to intervene on icy roads, but did its job and produced no disturbing feedback through the brake pedal."
All reviews highlight the Subaru Impreza for providing all-wheel drive. On the road, reviews like Kelley Blue Book find that "the minute the road conditions get slick, the all-wheel drive system comes immediately into play, and you can feel the extra traction as the vehicle muscles its way through the ever-deepening drifts."
