Now-a year-on from the launch of the redesigned E Class sedan, Mercedes Benz is rolling out similar upgrades to its E Class coupe and convertible.

The twins receive updated styling and new security technology for 2014, but do these changes add-up to a better motoring experience? Come with us as we discover.

Even though the overall contour of the E Class coupe and convertible carries over for your brand new model year, both cars have now been graced with the newest edition of Mercedes' design language. In advance that means a more competitive fender and LED "winged" headlights. Modifications to the back of-the vehicles are much less obvious, but the convertible and coupe get new - appearance taillights and an even more upscale looking lower fender for

The interiors of the E Class coupe and convertible also have been offered a once over for 2014, with a restyled centre stack and threepod gauge cluster as one of the most notable changes hailing.

Convertible and the E Class coupe score high marks for a recent leather covered dash, but as underwhelming other interior surfaces come across. The E Class' door tops would be completely okay in a $25,000 midsize sedan, but feel weird in an automobile that has a price north of $50,000. The E Class' aluminum trim does not actually move us, either, but other finishes will be on-the options list.

The E Class sedan is scheduled to lose its V8 option starting next year but, because of an 80 percent take speed, the 8 - cylinder will stay on offer forever in the coupe and convertible. Rated at 402 hp and 443 lb ft of torque, the 4.6L twinturbo factory really feels stronger than its numbers would imply. Our E550 coupe test car appeared to have pulling power everywhere in the rev band and had no difficulty keeping pace on the autobahn.

The E350 coupe and convertible will stay on for one more year in the US, but will be changed by the double-turbocharged E400 in 2014. The E400 loses half a litre of displacement in comparison with the E350 -- 3.0L vs. 3.5L -- but the double-turbos add up to much more electricity; 333 horsepower and 353 pounds-ft of torque, to be exact.

We could try a Euromarket E400 convertible and came away very amazed with the brand new engine. We did not detect any turbo lag and also the double-turbocharged V6 felt as powerful as a typical V8.

Both mills come mated to Mercedes Benz' seven speed automatic transmission.

In case you get tired of the E's steering completely, Mercedes' discretionary Intelligent Drive system can assume driving duties. We found the program worked well complete, but we did some to encounter wandering within the lane markers.

At autobahn speeds, the E coupe felt a bit more planted than its convertible counterpart, but than we were anticipating the droptop demonstrated much less flex. Whenever you eventually tire of the windin-your hair feeling, the convertible's triple layer soft top does an exceptional job of keeping surrounding sounds at bay.

But if you are merely in the marketplace for a high dollar blvd cruiser that goes like stink and seems great, the E Class coupe or convertible might be only the-car for you.
