Mercedes-Benz presents its first flex-fuel C-Class in the world

Mercedes-Benz has recently started producing its passenger cars for the second time in Brazil. The first attempt, with the A-Class, has been a huge failure, with a total production that was expected to be the year production of the facility. This one has more successful cars in the line, as well as a little “tropicalization”. The first ever flex-fuel C-Class will be produced in Iracemápolis, São Paulo, and will present exactly the same power of the petrol version. Another mistake, in our opinion.

Flex fuel cars are a great way not only to deal with expensive fuel prices, choosing ethanol or petrol depending on which one offers the best prices per km, but there is one more advantage in them: offer more power when ethanol is used. Since ethanol has a higher octane rating, engines that use it can have a higher compression ratio without knock risk, what allows for a better performance. Mercedes-Benz has preferred to be conservative, as has BMW with its flex-fuel engine. French automakers, such as PSA, have been more daring. The 1.6 THP engine, which normally offers 121 kW in its petrol only versions, can deliver 127 kW in its flex-fuel option in Brazil.

The flex-fuel C-Class version is the C 180. It uses the 1.6 4-cylinder engine that also powers the MFA family (A, B, CLA and GLA Classes). It pumps out 115 kW at 5,300 rpm and 250 Nm from 1,200 rpm up to 4,000 rpm.
