Tesla is hard at work on a new suspension setup for the Model S that will make the electric sedan even more of a competent handler and a car aimed squarely at enthusiasts.

The new suspension setup — which we sampled in our recent Model S review — will be an option offered only on the Performance version of the sedan. The upgrades include 21-inch rear wheels that are a half-inch wider than the those currently fitted to the Performance model, wrapped in stickier supercar-worthy Michelin PS2 tires. The air suspension remains intact, but revised suspension bushings and rear suspension end links are included in the package.

Elon Musk, Tesla's co-founder and CEO, told Wired that when he asked former Motor Trend editor in chief Angus MacKenzie what vehicle he'd driven recently that handled better than the Model S, MacKenzie cited the McLaren MP4-12C supercar. That prompted Musk and one of Tesla's suspension experts to rent a McLaren for a few days. Many of the Model S suspension upgrades were inspired by that drive.

A Tesla spokeswoman tells Wired that "We’re not positive if or when this 'performance plus' setup for enthusiasts will be available as an option, but as of today, we are testing various components to potentially offer it as an option for Model S Performance variants."

This new suspension would not affect acceleration performance or range, but would strictly be focused on enhancing the handling characteristics of the 85 kWh Model S Performance variant. And no, you won't be able to fit it to Model S sedans fitted with the upcoming 40- or 60-kWh battery packs.
