The refreshed K5 is a "versatile midsize" marvel. The new 2.5-liter engine has plenty of 4-star grunt for highway overtaking, and I’m averaging a decent 13 KM/L on long runs. The Bose audio and curved display make the cabin feel like a 5-star lounge. It’s a reliable, spacious sedan that looks aggressive but drives with total 4-star grace. Perfect for my cross-country trips.
