2014 Lexus IS-F Rumored to Trade V8 for Twin-Turbo V6

2014 Lexus IS-F Rumored to Trade V8 for Twin-Turbo V6

While far from confirmed, the latest rumors point to a twin-turbo V6 engine for the next-generation Lexus IS-F.

According to a report by Autoblog, when pressed on the issue, a Lexus representative commented that making such a switch does have obvious advantages.

Exactly what those advantages are is simple. The current 5.0-liter V8 makes 416-hp and 371 lb-ft of torque from a large displacement V8 engine. Switching to a smaller V6, perhaps a version of the brand’s 3.5-liter unit, and adding turbochargers could easily deliver the same horsepower numbers, with the added advantage of more torque.

But that’s not all. The smaller forced-induction engine should not only reduce overall vehicle weight, but should cut weight over the front axle, helping improve weight balance. And finally, a turbocharged setup would allow the car to significantly improve fuel economy – by as much as 20 percent.

Lexus, and parent company Toyota, has been lagging behind when it comes to internal combustion engine technology, instead opting to focus on improving its hybrid powertrains. According to a recent report by Automotive News, however, that is changing, with turbocharged engines on the horizon as the world’s largest automaker seeks to meet increasingly strict emissions targets.

    A rational judgement. Lexus seems to be on the mark, in my notion.
    I do see this new Lexus IS-F would take on from the BMW M3 to the brand-new Maserati Levante(2014 model) in near future!!
