Volkswagen has showcased an advanced 268bhp version of its turbocharged 2.0-litre four-cylinder diesel engine in a technical presentation at its Wolfsburg headquarters in Germany.
The power plant is expected to play an integral role in Volkswagen's efforts to meet tough CO2 emission targets that form part of new EU regulations set to come into force in 2020.
The new engine, described as a development of the existing EA288 unit used across the Volkswagen line-up, is claimed to deliver a 14 per cent improvement in power and economy over the most powerful variant of the Volkswagen diesel currently in production, the 237bhp engine recently unveiled in the Volkswagen Passat.
Among the developments brought to the new diesel is a two-stage electrically operated turbocharger, a piezo valve common rail injection system that operates at pressures of up to 2500bar and a newly engineered variable valve timing system.
With 268bhp, Volkswagen’s new 2.0-litre four-cylinder diesel engine kicks out 10bhp more than its recently updated 3.0 V6 diesel, as found in the facelifted VW Touareg.
