Redline Reviews takes an unusually honest look at a 2018 Corvette Grand Sport, calling out a cabin rattle most reviewers would gloss over while still framing it as the best-handling C7 built to date. A folding infotainment screen, real automatic-transmission feedback, and a subtle silver paint job round out a walkaround that’s aged better than most Corvette content from the same era.
Buick’s Grand Sport looked like just another understated mid-size coupe, but hidden under the hood was a factory horsepower rating that dyno testing proved was flat-out wrong. From the 401-cubic-inch nailhead that skirted GM’s own displacement rules to the Stage 1 package that quietly outran its own spec sheet, the Grand Sport built a reputation on performance nobody advertised. Read on to find out how Buick kept one of its quickest cars a well-kept secret for six model years.
The 2017 Corvette Grand Sport brought 460 horsepower and the Z06’s wide body for around $66,000. The refreshed Porsche 911 Carrera S made 420 horsepower from a twin-turbocharged flat-six and cost closer to $104,000. On the spec sheet that looks like a rout, and then the test results came back and refused to line up with the numbers. Here is where each car actually wins, and why the price gap does not settle it.
The C4-generation Corvette had something to prove — and it did, in ways most owners never fully realized. Between 1984 and 1996 it introduced a completely redesigned platform, brought in British firm Lotus Engineering to help build the 375-horsepower ZR-1, and quietly set a 24-hour, 175-mph endurance speed record along the way. A separately built twin-turbo version, the Callaway Sledgehammer, pushed even further, hitting 254.76 mph on a closed track. Read on to find out how an era known for plastic panels and a flawed anti-theft key also became one of the fastest Corvette generations ever built.
Is the naturally aspirated Corvette Grand Sport really a cut-rate imitation of the supercharged Z06, or is it a legitimate performance variant in its own right? This side-by-side breaks down what the two C7 Corvettes actually share and where they genuinely differ under the skin. See which one actually makes more sense for the money.
