What reviewers say

Reviewers agree the GLC has a roomy, eye-catching, technology-laden cabin, plenty of performance and plug-in hybrids with a long electric range. The common criticisms are a ride that is less comfortable than expected, especially on sports suspension, a drive that trails rivals and a high price; Carwow notes the plug-in hybrids lose boot space, and Autocar found some switchgear flimsy.
