    • How is the 2019 Mercedes-AMG C238 E53 4Matic cabriolet so fat, expensive, and slow? 4602 pound curb weight

      Let's not pretend the turbo engine era is about saving the planet and lowering emissions. The cars are getting so big and heavy that to improve performance they had to go to turbos. How else are you going to move an E-Class cabriolet that weighs as much as an E63 wagon?


      Seriously, the E43 cabriolet weighs 4602 pounds. That is roughly the same weight as an E63 AMG wagon. To put in other terms, it is 500 pounds heavier than the old and already heavy CLK63 AMG V8. To make matters worse, 54% of the weight is on the nose. Is Mercedes-AMG doing an Audi impression?

      No wonder it needs a turbo M256 3.0 I6 with electric assist to move it. Output is 429 horsepower with 384 lb-ft of torque. An electric motor provides 21 of those horses and 184 lb-ft of torque.

      Even with all that power and torque it only manages a 12.8 @ 107.5 in the 1/4 mile. That might sound decent but take into account the old 2007 CLK63 AMG would do low 12's at 117 miles per hour. That was done without turbos by the way.

      How is this progress when a naturally aspirated and lighter Mercedes CLK from over a decade ago crushes it in performance? Not to mention AMG has no real AMG model variant for the E-Class coupe despite them pretending the E53 is one. The M256 I6 is not an AMG motor folks.

      Maybe you're thinking the car is a value at least? Nope. The as tested price is over $100k with the starting price at over $80k.

      Sorry Mercedes. Not only does this car not deserve an AMG badge it's fat, overpriced, and it underforms.

      The BMW M4 convertible is quite simply a superior car in every respect.
