Subaru WRX S4 gets big power bump in Japan

A month after originally teasing it, Subaru is finally unveiling its WRX S4 model for Japan. It's a bit more than just a plush take on the sport sedan, because Subaru is fitting a more powerful version of the 2.0-liter, turbocharged boxer four-cylinder engine than we get on these shores.
The company says that S4 stands for "'Sports performance', 'Safety performance', 'Smart driving' and 'Sophisticated feel," and it certainly looks like this Rex ticks all of those boxes. The most surprising feature is the Japanese model's 2.0-liter turbo engine boasting 296 horsepower (221 kilowatts) and 295 pound-feet (400 Newton-meters) of torque in this application. That's quite a healthy upgrade over the 268 hp and 258 lb-ft that Americans get in the standard WRX, and it's even nipping at the heels of the 305 hp and 290 lb-ft from the STI with a 2.5-liter mill that we get over here.
While extra power is always welcome, enthusiasts might not be so thrilled that Subaru's Sport Lineartronic Continuously Variable Transmission is the sedan's only available gearbox. However, it offers a simulated eight-speed shifting mode when drivers notch the car into Sport# driving mode. Of course, the S4 also packs Subie's trademark all-wheel drive with Vehicle Dynamics Control and Active Torque Vectoring as standard.

New-gen 2020 Subaru Outback carries on its rugged legacy

The Outback is Subaru's best-selling vehicle, and for good reason. It's capable, it's versatile, it wears inoffensive looks, and it offers plenty of modern tech in a relatively affordable package. So when it came time to rework the model and introduce a new generation, Subaru took the less-is-more approach to the aesthetic redesign, which only has subtle tweaks. The major changes come inside the cabin and beneath the sheetmetal by introducing a more premium interior, and an all-new XT trim with a torquey new 2.4-liter turbocharged boxer engine. Similar to the approach used to update the 2020 Legacy, Subaru refined the Outback at every level. That started with the car's bones and the Subaru Global Platform. Subaru says the 2020 Outback is 70 percent stiffer in torsional and front-suspension rigidity and 100 percent stiffer in front lateral flex and rear subframe rigidity. The improved structure is also said to be 40 percent more absorbent in front and side crashes. More exciting is the introduction of multiple XT trims, which come standard with a 2.4-liter turbocharged boxer engine. Like the Legacy, the Outback is getting rid of the 3.6-liter six-cylinder engine in favor of the model's first turbocharged offering since 2009. It makes 260 horsepower at 5,600 rpm and 277 lb-ft of torque at 2,000 rpm, four more horsepower and 30 more lb-ft than the six-cylinder. Subaru notes the 2.4-liter engine offers a 3,500-pound towing capacity, which is an 800-pound improvement and the Outback's highest tow rating ever. It is estimated to get 23 mpg city and 30 mpg highway, compared to the 3.6's 20 mpg city and 27 mpg highway. All Outbacks come standard with permanent symmetrical all-wheel drive and a Lineartronic continuously variable transmission (CVT) that offer an "eight-speed" manual mode and paddle shifters. Base-model Outbacks continue to use a 2.5-liter naturally aspirated boxer engine, which Subaru says has 90 percent new parts. Its specs increase to 182 horsepower at 5,800 rpm and 176 lb-ft of torque at 4,400 rpm from 175 horsepower and 174 lb-ft in the previous model. With the slight increases in power comes a lighter and more agile suspension. Up front the Outback will have MacPherson struts with an internal rebound spring and a new 0.9-inch hollow stabilizer bar. In the back, a double wishbone setup with coil springs and a 0.75-inch hollow stabilizer bar. Overall, the Outback maintains its impressive 8.7 inches of ground clearance.

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.
