Dynamic to drive, extremely efficient and exemplarily clean are apt descriptions for both diesel models – in the CLA 200 CDI and the CLA 220 CDI, which is available exclusively in combination with the dual clutch transmission 7G-DCT. Both engines have a displacement of 2.2 litres.

The engine in the CLA 200 CDI has an output of 100 kW (136 hp) and a maximum torque of 300 Nm. The combined fuel consumption, from 3.9 litres of diesel per 100 kilometres (CLA 200 CDI with 7G-DCT, with a manual transmission: 4.1 l), is excellent for this output class.

The 130 kW (177 hp) top diesel in the CLA 220 CDI has a maximum torque of 350 Nm. The performance, including 8.3 seconds for the standard sprint and 228 km/h maximum speed, is at a sporty level. With 105 g CO₂ per kilometre and combined consumption of 4.0 l/100 km the CLA 220 CDI also sets benchmarks in its segment.

The CLA 200 CDI and CLA 220 CDI are categorised in efficiency class A+. All-wheel drive variants in the form of the CLA 200 CDI 4MATIC and CLA 220 CDI 4MATIC will follow in September 2015.

An overview of the data for the CLA with a diesel engine:

Figures for version with 7G-DCT dual clutch transmission in parentheses;

The entry-level model in the petrol range is the CLA 180, whose 1595 cc engine boasts a rated output of 90 kW (122 hp). The state-of-the-art four-cylinder unit offers a maximum torque of 200 newton metres, which is available in a wide engine speed range from 1250 to 4000 rpm. The fuel consumption and CO₂ emissions, at 5.3 l/100 km, NEDC combined, and 124 g/km respectively, are at a record-breakingly low level (data for version with 7G-DCT, values for manual-transmission variant: 5.5 l/100 km/128 g/km).

The CLA 200 with a displacement of 1595 cc also develops 115 kW (156 hp) and maximum torque of 250 Nm, which is also available from 1250 to 4000 rpm. It sprints from zero to 100 km/h in 8.7 seconds and has a top speed of 225 km/h, but gets by on an average of 5.3 l/100 km of fuel, meaning CO₂ emissions of 124 g/km (data for version with 7G-DCT, values for manual-transmission variant: 5.6 l/100 km/130 g/km).

The sportiest engine this side of the CLA 45 AMG, with a displacement of 1991 cc, is the CLA 250. The engine develops 155 kW (211 hp) and maximum torque of 350 Nm from 1200 to 4000 rpm. Performance is at sports car level, with acceleration from 0 to 100 km/h in 6.9 seconds and a top speed of 240 km/h. Nonetheless it has the best fuel consumption in this class at 5.5 l/100 km and CO₂ emissions of 128 g/km.

All-wheel drive is available straight from the market launch in the CLA 250 4MATIC and CLA 250 Sport 4MATIC (features include: dynamic styling, sporty tuning of engine, accelerator and transmission as well as sporty engine sound; see model chapter).

All-wheel drive is of course also standard with the CLA 45 AMG top model (see separate press kit).

A comfortable yet dynamic driving style is possible thanks to the dual clutch transmission 7G-DCT and the six-speed manual transmission. The 7G-DCT dual clutch transmission is extremely compact, extremely variable with regard to adaptation of the engine speed thanks to seven gears, and incorporates an electric oil pump for start/stop capability. It shifts gears without any interruptions in tractive power and combines the comfort of an automatic with the efficiency of a manual transmission. The 220 CDI and CLA 250 plus all the 4MATIC variants are equipped as standard with the 7G-DCT transmission, which is optionally available for the CLA 200 CDI, CLA 180 and CLA 200 CDI.
