Porsche regained the top spot in J.D. Power's annual study of new-vehicle appeal, nudging past BMW and 2018 leader Genesis, while Ram led mass-market brands and was the most improved marque from last year. Last year Genesis snapped Porsche's 13-year streak in the No. 1 spot.
Luxury brands again dominated J.D. Power's Automotive Performance, Execution and Layout Study, which was released Wednesday. Following the top three brands were Audi, Volvo, Land Rover and Lincoln.
The study measures vehicle owners' emotional attachment and level of excitement with a new vehicle across 77 features and can help automakers reevaluate the design or redesign of cars and light trucks. Brands are scored on a 1,000-point scale.
