* Horsepower and torque expected to top
previous model (testing is ongoing — check media.gm.com for updates) * NOx emissions reduced at least 63 percent
over 2010
models * Quieter operation * High - pressure (30,000 psi / 2, 000 bar) Piezo - actuated fuel system for greater fuel efficiency, improved performance and reduced emissions * Exhaust brake system that enables controlled vehicle slowdown on downhill grades without actuating the brakes * Selective catalytic reduction after - treatment system using diesel exhaust fluid (DEF) injection to provide the best overall diesel characteristics and performance — with a range of about 5,000
miles (8,000 km) between DEF refills * Combustion and after - treatment have been optimized to provide about 700
miles (1,125 km) between diesel particulate filter regenerations — a 75 - percent
improvement over the
previous system and significant contributor to improved fuel efficiency, as the regeneration process requires additional fuel * B20 biodiesel capability for an alternative fueling option * Internal revisions that improve durability
Green Car Reports praised this year's
model's
improvements for boosted battery life by saying, «That's a 50 - percent increase
over the
previous model's 83
miles, and significantly increases the practicality of the e-Golf for drivers with longer commutes — or those who live in areas with winter weather.»
