In our tests, the IS came up short as a sports sedan. Handling is secure but not engaging enough to run with true sports sedans. Ride comfort is neither tied down nor plush. Even the punchy IS 350 is underwhelming to drive. For 2016 a new 255-hp V6 powers the IS 300. It gives the car more zip, but its fuel economy of 20 mpg overall is uncompetitive in the class. Still, the interior is extremely cramped, and getting in and out is an ungraceful chore. All-wheel-drive versions have a pronounced hump by the driver's right leg. Fit and finish is okay but not a standout, and the mouselike infotainment controller is distracting to use. A new 2.0-liter turbo four-cylinder is available, but only in rear-wheel drive. Reliability has been above average, but the IS scores too low to be recommended.
