Looking for a four-door that combines both sportiness, luxury, and practicality? Jaguar might have what you're looking for with the XE. It may be the smallest sedan in the automaker's lineup, but it's also the company's sports sedan. With its sleek lines, driver-centric cabin, and a generous amount of standard amenities, the Jaguar XE combines sporty driving with cutting-edge tech. A 2.0-liter turbocharged diesel engine powers this particular cat, and is mated to an eight-speed automatic gearbox.
