Even car companies have reason to worry about their report cards.
The magazine's Top Picks and Brand Report Cards are a set of ratings for vehicle quality that are scrutinized by new-car buyers just as thoroughly as stern parents pore over grade-school report cards.
The award for the Tesla may not be too surprising, given the magazine's ongoing love affair with the Model S.
When it joined the Consumer Reports' fleet last year, the all-electric Model S luxury sedan became the highest-rated car tested since 2007, and it has continued to impress the staff.
The Prius has held that title for 11 consecutive years, and in fact only one other car--the 2003 Honda Civic Hybrid--has ever received the award.
However, the addition of the Ram 1500 pickup truck to Consumer Reports' Top Picks list was surprising.
Named Best Pickup Truck, the Ram was the first Chrysler product to make the list in 16 years.
The magazine's praise for the Model S and Ram 1500 indicate that Japanese carmakers' grip on the Top Picks list is beginning to loosen--but the Brand Report Cards tell a different story.
Lexus got top marks for the second year in a row, followed by Acura and Audi.
In fact, seven of the top eight spots were held by Japanese brands.
Meanwhile, Jeep and Ford tied for the lowest score; fellow Detroit brands Dodge, Cadillac, and Chevrolet rounded out the bottom five.
