Lexus V8s power into the future

Upcoming RC F coupe is the most potent Lexus V8 yet.

Prestige makers such as Lexus are taking over from Ford and Holden as custodians of Australia's V8 heritage.

An all-new Japanese road runner, the Lexus RC F coupe, is just around the corner and it's all about the performance package centred on its V8. The engine is the most powerful yet from Lexus, which has had a smoothly efficient V8 at its heart since the original LS400 in 1989.

The new 5.0-litre V8 is packing more than 330kW and 520Nm of torque, figures set to run it head-on into the latest BMW M4 coupe and next year's all-new Mercedes-Benz C63 AMG. We will have full details later this week after the global press preview drive of the landmark two-door in New York.

"There is definitely a 5.0-litre V8 coming in the RC," says Lexus Australia spokesman Tyson Bowen. "It will produce more than 300kW and more than 500 Nm, yet deliver fuel efficiency better than 11.4L/100km The V8's output is not a threat to the supercharged 6.3-litre V8 in the HSV GTS, which makes 430kW.

However, the difference is the Lexus engine has a future well beyond the end of local production of the Ford Falcon and Commodore. The V8-powered headliners from the red and blue teams are selling as well as ever, and better than ever if they have an HSV or FPV badge, but their time is running out.

That means a V8 future in Australia is likely to wear an upscale badge from a brand such as Lexus, or Benz or BMW, or perhaps even Infiniti. Add to that performance brands such as Porsche and Aston Martin. And there will be V8s, including diesels, in top-end four-wheel-drive tow machines including the Range Rover, Toyota LandCruiser and the latest - pricey and unpopular - Nissan Patrol.

Lexus says there is an obvious appeal in V8 engines, which is why it already has three V8-powered models - the LS, IS and LX SUV - in its Australian line-up. "We have V8s for a number of reasons. In the IS F it's all about performance and the visceral sound performance and acceleration that comes with a V8," Bowen says. "In the LS it's a slightly different proposition, because V8s are smooth and efficient. They are not stressed because they are not driven as hard.

"In the LX, it's about the flexibility and torque for low-end pulling power for towing, and the efficiency at cruising speeds."Bowen is not going into detail on the RC F, even though it's less than a week away from the public spotlight, but he is happy to discuss the Lexus obsession with V8s. "The original proposition was about the quietness, efficiency and refinement when you go back to the original LS 400 in 1989.

Remember they famously balanced a coin on the engine to highlight its smoothness, they stacked a pile of wine glasses for a television commercial. They also use that 4.0-litre V8 in ultralight aircraft, because it can run so lean and for so long without troubles."
