Audi’s newest A4 is impressive in standard guise, but it really comes alive in S4 form. Under the hood is a turbocharged 3.0-liter V-6 that dishes up 354 horsepower, though sadly it can only be had with an automatic transmission. Purists should look elsewhere.

Chevrolet has some racy editions of the Suburban and Tahoe. The big SUVs finally ditch their anemic 5.3-liter V-8s in favor of the 6.2-liter mill found in the related Cadillac Escalade and GMC Yukon Denali, and that’s just the start of the upgrades.

Subaru’s Outback receives some updates for 2018. The changes are similar to what’s found on the 2018 Legacy.
