Yonkers, New York – Convertible versions of the Infiniti G37, Lexus IS 250 and Audi A5 all scored “Very Good” overall to take the top spots in tests by Consumer Reports.

The Mazda MX-5 and Mini Cooper S convertibles were also tested, along with three sporty cars: the Volkswagen GTI, Mazdaspeed3 and Mitsubishi Lancer Ralliart for the magazine’s May 2010 issue.

The G37 and IS 250 scored “Very Good” road tests of 77 points, while the Audi A5 received 74 points. All three fall among the better models in the category, including the previously-tested Volkswagen Eos at 78 points, and the BMW 328i at 76 points. The MX-5 scored a road test of 89 points, while the Mini Cooper S scored 77 points. The testers said that the G37 hardtop is based on the G37 sedan, which is consistently a top performer in its tests. The IS 250 is “pleasant and refined, but it’s not as sporty,” while the A5 is “stylish and luxurious, and its soft top can be operated on the move.”

Among the five convertibles, only the MX-5 rates a “recommended” score. Consumer Reports only recommends vehicles that have performed well in its tests, have at least average predicted reliability based on its annual auto survey, and performed at least adequately if crash-tested or included in a government rollover test. The magazine said it doesn’t have sufficient reliability data on the other four models.

In the sports car tests, the Volkswagen GTI led with an “Excellent” road test score of 85, followed by the updated Mazdaspeed3, which also rated “Excellent” at 83 points. The Ralliart trailed with a “Very Good” score of 72 points.
