Subaru takes another look back, this time at the 2004 WRX STI

Here we have the followup to the rally-mimicking Impreza 22B STI that Subaru recently chronicled in its Vintage Garage series: the 2004 Impreza WRX STI. Displacement for the boxer four was upped from 2.2 liters to 2.5, and after noticing how many buyers had installed larger turbochargers on their WRXs, Subaru decided to bolt on one in-house. That gave the final product 300 horsepower and a 0-to-60 mile-per-hour run of just 4.6 seconds.
It was stiffer, it's body from nose to front doors was penned by Peter Stephens, he of the McLaren F1, it came with a driver-controlled center differential, driver-activated cooling spray for the turbos and 300 pound-feet of torque. This is a curio from a time when, after a new WRX STI came out, you started poring through magazines to see how the Mitubishi Evo was going to respond. You can find out more about it in the video below.

Subaru might build WRX hatchback after all

The 2015 Subaru WRX is awesome. Really awesome. We told you as much in our first drive of the new sedan back in December. Honestly, our only complaint about Fuji Heavy's new performance machine is that it's no longer offered as a hatchback - the new WRX is a sedan-only affair, despite the more functional five-door variant accounting for some 50 percent of sales in the car's last generation.
But there's hope on the horizon, if a report from Australia's Motoring.com is to be believed. Speaking with Masuo Takatsu, Subaru's general manager for the WRX, the company is now re-considering putting the "hatch" back in its hot hatch.
"We have received strong interest from the US, where the hatchback was 50 percent (of previous-generation WRX sales), so we're now considering," Takatsu told Motoring, noting that the United States is Subaru's main target for this car. Additionally, Takatsu said the company's decision to only offer the sedan was the result of limited engineering resources, echoing statements we've previously heard from Subaru's US arm.

Subaru uses a mime and a toy car to explain why it loves the boxer engine

I will freely admit to struggling with why Subaru continues to stubbornly employ a boxer engine design while so few other automakers do the same. After all, with twice the number of cylinder heads and cams as a traditional inline four-cylinder engine, a boxer four is more complex, more expensive to manufacture and more cumbersome to service with few tangible benefits. Until recently, the company's engines struggled to meet the fuel economy numbers of its competitors while offering no real boon in horsepower or torque. Subaru seems to recognize I'm not the only one scratching my head.
In order to help us non-believers understand what's what, the company has employed a pair of mimes, a toy car and a few clay engines to demonstrate the folly of every other automaker on the planet. Subaru says the boxer offers up a lower center of gravity than either an inline four-cylinder engine or a V6, which I will gladly concede. The company also says the design offers up smoother operation.
I'll offer just two counterpoints here. First, an engine with a low center of gravity is excellent, but when vehicles like the Forester, XV Crosstrek and Outback boast more ground clearance than most mainstream SUVs, that argument flies out the window. Second, anyone who's spent any amount of time behind the wheel of a vehicle equipped with an inline four and then proceeded to move into one propelled by a boxer can tell you the latter has all of the idling manners of a small tractor.
