The wheelbase now stands at 105.1 inches, Subaru says, up from 103.9 inches, with rear seat legroom growing by 1.4 inches.
Subaru says the Forester will be more spacious overall, especially when it comes to headroom as well as hip and shoulder room.
Subaru will offer five trims for the 2019 model year: standard, Premium, Sport, Limited and Touring.
All Foresters will be powered by the same engine, a freshened 2.5-liter four-cylinder boxer engine that produces 182 hp and 176 pound-feet of torque, up from 170 hp and 174 pound-feet.
The Forester will be available with a continuously variable transmission only.
Sport and Touring trims, Subaru noted, will have a manual mode that "simulates a seven-speed manual transmission," thanks to steering-wheel paddle shifters.
The Sport trim is new and features exclusive design touches that include a black gloss grille, black 18-inch wheels and orange accents throughout the exterior and interior.
The previously offered XT trim and its turbocharged engine did not make the jump with the redesign.
Standard safety features
As with the upcoming Ascent, Subaru's EyeSight driver-assist technology, which is highlighted by automatic pre-collision braking, adaptive cruise control, lane-departure and sway warning and lane-keep assist, among other features, is now standard across all Forester trims.
Standard on the Touring trim is a new safety feature Subaru has named DriverFocus.
Combined with EyeSight, DriverFocus "is a monitoring system that uses facial recognition software to identify signs of driver fatigue or driver distraction," Subaru said.
The feature, which the automaker claims is the first in the segment, can recognize up to five drivers and can remember their presets for seat position, climate and infotainment.
