The sporty Jaguar XK coupe and convertible come
in three trim levels: basic, R and RS. Their 5.0L V8
engines produce anywhere from 385 to 510 to even
550 horsepower. All are matched with a 6-speed
automatic transmission. The XKR-S convertible
is new for 2013. These coupes and convertibles can
accommodate four passengers, though the back seats
are not terribly comfortable.
