The Subaru Forester leverages an efficient 2.5 Liter engine to deliver fuel efficient transport in the mid-size SUV segment, without hybrid powertrain components. In fact, the Forrester’s light weighting strategy gives it a significant weight advantage across the segment, coming in at 875 pounds lighter than the average curb weight in class. Less resources translates to reduced environmental footprint, increased operational efficiency and reduced life-cycle operating costs.
The Subaru Forester performed well in the Automotive Science Group’s (ASG) 2018 Automotive Performance Index™ (API), demonstrating the economic efficiencies of Subaru’s SUV platform. With an EPA estimated 32 MPG highway (26 city/32 hwy/28 combined), the Forester outperforms competitors in class by an average 6 MPG highway, revealing impressive fuel economy and reduced fuel costs in the SUV segment, earning ASG’s 2018 BEST 5 ALL-AROUND PERFORMANCE Award.
ASG’s all-around performance analysis is a comprehensive data-driven assessment, analyzing economic, environmental and social performance indicators across a vehicle’s life-cycle, and in relative comparison to all 372 SUVs assessed.
The Forester also earned a class leading economic performance rating in ASG’s Study, outperforming all vehicles in its segment, and earning ASG’s 2018 BEST ECONOMIC PERFORMANCE AWARD in class. ASG found the Forester to cost 35% less to purchase and operate in the first 6.5 years of its life-cycle, when compared to the average vehicle in the mid-size SUV class. The Forester lead notable competitors including the Dodge Journey with a 6% advantage, the Hyundai Santa Fe Sport by 8% and the Nissan Murano and Ford Edge by 20% and 21% respectively.

The Automotive Performance Index (API) applies statistical methods to demonstrate each vehicle rating in relative comparison. For example, the vehicle that performs highest in environment performance in a given class obtains a rating score of 100. Each vehicle in its class is then compared relative to the top-performing vehicle with a rating score reflecting the statistical difference in performance outcomes. A score of 91 translates to a 9% environmental performance deficit as compared to the top-performing vehicle.
Due to the API’s relative vehicle rating method, vehicle class divisions were identified as a critical input - these class divisions are detailed here.
While the Automotive Performance Index is indeed an exhaustive list of vehicles to trim level detail, with each vehicle assessment reporting over 200 unique data outputs (the culmination of thousands of data inputs), ASG has taken additional measures to ease the burden of sorting through all data points and all vehicle assessments. We have developed key performance categories and sorted all vehicles in each class according to Environmental Performance, Social Performance, Economic Performance and All-Around Performance. The vehicle in each class with the best score in each unique category is named the performance award winner (i.e. Best Environmental Performance Award winner). The vehicle in each class that scores highest combined scores in Environmental Performance, Social Performance and Economic Performance is named the ASG Best All-Around Performance Award winner.
One step further, we also name the Best 5 All-Around Performance Award winners in each class to provide consumers with a concise product comparison guide.
