With the Detroit auto show already growing smaller in the rearview mirror, the next big show of the 2014 season is underway in Chicago. The noticeably confident Detroit automakers may have received most of the attention at the show in their hometown, but this week, on the other side of Lake Michigan, the spotlight was on foreign manufacturers.

Here are the highlights from the Chicago Auto Show:

■ Subaru unveiled an updated version of its Legacy sedan, promoting its improved fuel efficiency over the outgoing model. The fuel-economy figures are still estimates, but Subaru says the 2015 Legacy 2.5i, which gets a 175-horsepower 4-cylinder boxer engine, will achieve 26 miles a gallon in the city and 36 on the highway, for a 30 m.p.g. combined figure. The 256-horsepower 3.6-liter 6-cylinder boxer-equipped model achieves an estimated 20 m.p.g. in the city, 28 highway and 23 combined. A continuously variable transmission and all-wheel drive are standard for all trim levels.

■ Nissan introduced a diesel-power Frontier concept pickup and the 2015 Nissan Versa Note SR. The diesel Frontier, equipped with a roughly 200-horsepower 2.8-liter 4-cylinder Cummins turbodiesel, is based up the gasoline-power Frontier Desert Runner 4x2 model. Nissan says its aim is to gauge interest in a diesel-power small truck.

The 2015 Versa Note SR is Nissan’s sporty take on the subcompact hatchback and features special styling cues to differentiate it from its more pedestrian brethren. Although the front-drive SR’s Xtronic C.V.T. and 109-horsepower 1.6-liter 4-cylinder engine may not be considered very sporty to some drivers, the car does achieve estimated fuel economy of 31 m.p.g. in the city, 40 on the highway and 35 combined.
