Volkswagen Group’s W12 engine has been with us for over 13 years now, but the unique powerplant has remained competitive throughout in regards to both performance and fuel economy. This is because VW has consistently upgraded the engine through a series of revisions, with the latest being announced at the Vienna Motor Symposium in Austria.
The new 6.0-liter W12 engine produces 600 horsepower from 6,000 RPM and 663 lb-ft of torque from 1,500-4,500 RPM, and VW claims the fastest model to receive the mill will scoot from 0-60 mph in under four seconds. Those figures are nothing groundbreaking for individuals familiar with the W12’s capability, with the real strides being made in emissions and fuel economy returns.
VW says the W12 TSI will be the most fuel-efficient twelve-cylinder engine available in a luxury car. Exact MPG returns have yet to be announced, however VW claims it will emit just 250 grams of C02 per kilometer, which is roughly equivalent to 21 MPG US. Many small upgrades can be attributed to fuel economy gains, however cylinder deactivation and a standard start/stop system are two of the most crucial aspects of keeping the W12 as efficient as possible.
It’s unclear what applications the W12 TSI will be used in, however we’re betting future Bentley models will receive a variation of the engine along with the next-generation A8L sedan. There’s also been whispers of a new VW Phaeton coming along and we’d be surprised if we didn’t find the new W12 hiding under its hood when it comes to fruition.
