The BMW 340i will feel more refined, more polished and will handle better from the factory if you check the box for the premium summer tires — but the Q50 is quite simply more fun. The stock choice and abundant low-end power combined with a stability control program that’ll let you get a little sideways before stepping in made me giggle like a 12-year-old schoolgirl. (Maybe I shouldn’t admit that.) While the BMW is buttoned down in appearance and manner, the Q50 is eager and just a little insane. And that’s how I like my cars. If you wax poetic about your first Infiniti G sedan, this is the replacement.
