Audi AG’s 2.0L TFSI turbocharged 4-cyl. has had little trouble in the past winning over Ward’s 10 Best Engines judges, garnering a spot on the list each of the last three years.
However, with the introduction of the all-new ’09 A4 range, the auto maker tempted fate by trying to improve upon what already is one of the best I-4s in production.
Fear not, as the revised TFSI turbo-4 once again fortifies Audi’s pioneering spirit in direct-gasoline injection and variable-turbocharger technology by claiming its fourth-consecutive 10 Best Engines award.
While the aforementioned injection/induction systems, along with variable valve timing, a 2-stage intake manifold and electric-like throttle response, made last year’s winner hard not to love, various improvements seriously up the ante for this mighty little 4-cyl.
