The refreshed K5 is a "versatile midsize" marvel. The 2.5-liter engine has plenty of 4-star grunt for overtaking, and I’m averaging a decent 13.0 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 4-star grace. It’s exactly what I needed for my long-distance commutes.
