10-speed DSG previewed

Volkswagen has introduced a high-powered four-cylinder 2.0-liter turbodiesel engine during a technical presentation held at home in Wolfsburg, Germany.

A few months ago, Volkswagen came out with the all-new Passat which among many engines is offered with a four-cylinder, 2.0-liter TDI bi-turbo rated at up to 240 HP (176 kW). The same engine has now received a two-stage electrically operated turbocharger which has managed to bump output to 272 HP (200 kW). There's no word yet about the torque figure yet but chances are it's a bit higher than the 500 Nm (369 lb-ft) available in the Passat.

The additional power was obtained not only by implementing an electric turbocharger but also by installing a new variable valve timing system and a Piezo common rail injection system working at pressures of up to 2,500 bar.

Volkswagen has also provided some preliminary details about its forthcoming 10-speed DSG transmission which will be able to cope with up to 550 Nm (405 lb-ft) of torque. Codenamed DQ551, the ‘box is actually an evolution of the six-speed unit and will feature a coasting function to save fuel along with a new brake energy recuperation system which promises to be more efficient than before.

A ridurre/eliminare il ritardo di risposta sui motori turbocompressi;)

Imho con il passare degli anni diventerà una tecnologia sempre più diffusa sulle auto di serie di un pò tutti i marchi,a cominciare da quelle più care.

Con l'avvento dei micro ibridi e degli impianti elettrici a 48 V, sarà un complemento che aiuterà a ridurre consumi e ad aumentare la piacevolezza di guida.

Anche Kia di recente aveva presentato un prototipo, senza esagerare con la potenza però: http://www.autopareri.com/forum/concept-anteprime/67413-kia-optima-t-hybrid-concept-2014-a.html ;)

Volvo invece ha fatto proprio una sboronata: http://www.autopareri.com/forum/meccanica-ed-innovazioni-tecniche/67495-volvo-high-performance-drive-e-2-0-quattro-cilindri-triple-boost-450-cv.html :)

Se utilizzano questa tecnologia in modo ''maldestro'' pimpando ancora di più i 4cil. è assai probabile che sostituiranno i 6cil fino a 300cv o quasi....se utilizzano questa tecnologia solo per migliorare l'erogazione,consumi e il piacere di guida sarebbe meglio imho.
