A twin-turbo V6 engine is rumored to soon be available on the next-generation Lexus IS-F. However, this has yet to be confirmed. A Lexus representative told Autoblog that there are clear advantages in making the switch. It’s currently being powered by a 5.0-liter V8 with an output of 416-hp and 371 lb-ft of torque from a large displacement V8 engine.
Making the switch to a smaller V6 engine, probably a variant of the brand’s 3.5-liter unit, and installing turbochargers may easily offer the same horsepower figures, with the additional benefit of more torque. Furthermore, the smaller forced-induction engine doesn’t just decrease the overall vehicle weight, but should cut weight over the front axle, helping to boost weight balance.
Lastly, a turbocharged setup will enable the car to boost fuel economy significantly by up to 20%. When it comes to internal combustion engine technology, Lexus and its parent Toyota have been falling behind rather than focusing on advancing its hybrid powertrains.
Automotive News is saying that this is changing as turbocharged engines may soon arrive in the foreseeable future as Toyota aims to comply with increasingly stricter emissions standards.
