Both of those pieces of news are likely to boost the appeal of Jag’s hot-selling sports-car. But there’s one more piece of news for the 2016 F-Type that might not be received quite as well by enthusiasts: Electric power steering is arriving to the lineup.
But according to the F-Type’s chief engineer, Russ Varney, if they’ve done their job right you won’t notice all that much of a difference in the 2016 F-Type with electric assist, versus the 2014 and 2015 models with hydraulic assist.
“We’ve had a long relationship with ZF with the hydraulic systems, and they know how we tune our gear, so it was natural
progression,” said Varney, who described the ZF-supplied electric system as one that was ‘bespoke,’ and tuned by Jaguar engineers.
“When we first launched F-Type, we weren’t completely convinced that EPAS technology had advanced well enough to be deployed in the F-Type,” said Varney. “So we launched with the hydraulic system, and it was a system that we knew very well.”
“What it gives us the opportunity to do is to take that last one percent of tuning, to make sure that every application is as good as the best one.”At present there are three different calibrations for the F-Type, Varney explained, although they could have one for every option and tire variant if needed.
Engineers went into the project with very objective criteria of how Jaguar steering should be. “We’ll map out what we want the steering weighting to be in certain conditions at speeds, what the yaw gain should be...and we’ll set ourselves a window of operation for what we need to get into.”
Varney confirmed that the systems in the F-Type and the system in the upcoming XE have different ratios and are different part numbers, but they were developed at the same time.
And he cautioned that electric steering can’t simply be ‘plugged in.’ Suspension geometry, weight distribution, and the stiffness of the body structure all factor into steering feel, too, Varney explained, and that can’t be underestimated.
