It's a bold move byMotor Co. Ltd. to roll out a new V-8 in a time of economic downturn and fuel conservation.
Yet, the new Tau 4.6L DOHC V-8 scores a first-time Ward's 10 Best Engines appearance for the South Korean auto maker with an impressive mix of power, efficiency and affordability.
Unanimously praised for being a ton of engine for the V-8 Genesis sedan's sub-$40,000 asking price, the Tau represents's longing to undercut the price of established luxury-vehicle players, while also flexing its engineering muscle.
With high levels of refinement permitting creamy runs up the powerband, the Hyundai V-8 feels much like the 4.6LMotor Corp. and Corp. Northstar V-8s that influenced its design.
However, variable intake and valvetrain systems, as well as other advances in internal components, allow the 375-hp Tau to outperform all of its mid-level luxury rivals, including in the area of fuel economy.
And most of those rivals, namely from, Mercedes-Benz and Lexus, are considerably more expensive than the $54,000 price cap afforded to 10 Best Engines entrants. Despite being a little short on emotion, the Tau is a triumph for an auto maker venturing for the first time into the luxury market.
