CLA 45 AMG Shooting Brake from standstill to 100 km/h
in 4.7 seconds. At the same time, the fuel consumption of
just 6.9 litres for every 100 kilometres (NEDC combined)
also underlines the trailblazing standards of efficiency
achieved by Mercedes-AMG.The list of technical highlights also includes the AMG SPEEDSHIFT DCT 7-speed
sports transmission, fully variable AMG Performance
4MATIC all-wheel drive, the powerful braking system and
a chassis that has been purpose-developed, from the
tuning set-up right through to the axles.
As a high-performance engine belonging to the
BlueDIRECT family, the AMG 2.0-litre four-cylinder turbo
engine features spray-guided direct petrol injection via
piezo injectors positioned centrally in the four combustion chambers with an injection pressure of 200 bar.
The combination of multiple fuel injection and multiple
spark ignition improves fuel economy and significantly
increases thermodynamic efficiency, leading to low exhaust emissions. The CLA 45 AMGShooting Brake therefore already complies with the Euro 6 emissions standard,
including the limit for maximum particulate emissions
that comes into force from 2016. In June of this year,the
four-cylinder turbocharged engine achieved a memorable double at the “Engine of the Year Awards 2014” by
winning the “New engine 2014” and “1.8-litre to 2-litre”
categories. As far as its technology is concerned, the AMG
2.0-litre turbo unit is related to the 4.0-litre V8 biturbo engine in the new Mercedes-AMG GT that delivers up to
375 kW (510 hp).
A twin-scroll turbocharger, maximum dethrottling
of the exhaust system and an innovative new injection
strategy result in an instantaneous build-up of charge
pressure and swift generation of high torque from low
revs. A positive side-effect: fuel consumption and exhaust
emissions also benefit from twin-sc
