The popular survey, run by magazine Auto Express, gives car owners the chance to rate their vehicles in 10 categories including reliability, running costs, practicality and in-car tech.
And this year's results suggest it's not just the low running costs offered by electric and hybrid cars attracting drivers - with a hybrid in first place and two electric vehicles in the top 10 for the first time ever.
The Lexus IS Mk3 was crowned the UK's favourite car with a satisfaction rating of 93.96%, ending the Skoda Yeti's three-year stint at the top. It ranked number one overall and also won the ease of driving category.
Three-quarters of all Lexus IS owners who took part in the survey - which received a record 61,113 responses, up 20% on 2014 - own the eco-friendly hybrid version. The new Lexus NX, also sold in hybrid form, finished sixth.
Two electric vehicles, the Renault Zoe and Nissan Leaf, came in fifth and eighth place respectively. The Zoe scored higher than the Driver Power 2014 winner, the Skoda Yeti, with a satisfaction rating of 92.87% compared to 92.78%.
The Skoda Yeti finished second in the latest awards, followed by the Hyundai i10 in third.
The Seat Leon Mk3, Jaguar XJ Mk4, MINI Mk3 and MG3 also featured in the top 10.
But there was no place at the top for the biggest-selling car in the UK - the Ford Fiesta - which finished back in 52nd.
The Audi A5 Sportback was the most improved car in Driver Power 2015, as it jumped 80 places from 106th to 26th. The Seat Leon, however, plummeted by the biggest margin - down from 65th to 192nd.
Lexus was voted the UK's favourite manufacturer, as it received a grand total of eight Driver Power awards.
Toyota was the most popular manufacturer with 13 models in the top 200, while Mini was named the most improved manufacturer.
