Mid-sized D-Class cars are considered larger cars in the European market and one of the more popular engine sizes in these cars are 2.0L gas engines. With the onset of new EU CO2 emissions limits in the next few years the 2.0L gas engine is expected to become a thing of the past in that class. The recently launched Ford Mondeo currently offers 2.0L and 2.3L four cylinders and both are likely to be replaced by a new 1.6L turbocharged four cylinder.
Ford hasn't released any details of the new engine yet but other companies are getting outputs in the same 120-160hp range of the 2.0-2.3L engines from 1.6L turbos. The advantage of the smaller engines such as the Volkswagen TSI are that they achieve similar power with considerably lower CO2 output especially when direct fuel injection is used.
