Long a benchmark midsized luxury sedan, the E-Class combines a feeling of substance and class with enjoyable and agile handling. Luxury-trim versions have a smooth and cushy ride, while the Sport is considerably firmer. The responsive 3.5-liter V6 and seven-speed automatic returned 21 mpg overall. We also tested a four-cylinder diesel, which got an excellent 30 mpg overall, with a range of more than 800 miles. The interior is plush, with excellent seats and fit and finish. A coupe, convertible, and wagon (with a rear-facing third row) are also available, as is an all-wheel-drive, high-performance E63 AMG sedan. Reliability has been average. A 2017 redesign goes on sale this summer.
