Amid the pandemic, and apart from an aerodynamic rule change, chassis design has been essentially paused between 2020 and 2021 apart from a complex ’token’ system.
However, as a technical partner of Mercedes’, Aston Martin got the green light to upgrade to the 2020 title-winning rear-end without spending a single token.
A similar rear-end upgrade would also have been available to Alpha Tauri.
"We decided to leave the rear of the AT01 as it is," said Alpha Tauri technical director Jody Eggington.
"It wasn’t an easy decision," he told the Japanese source as-web.jp. "We considered the positive and the negative sides.
"It was certainly an attractive option to switch to a new gearbox without using tokens, but it was the front of the chassis that I most wanted to develop."
Eggington said the decision was also guided by the sweeping new regulations for 2022.
"Next year’s cars will be drastically different," he said. "So we have to concentrate our resources there as well.
"Last year’s AT01 was very complete - especially the rear stability was fully satisfactory. So we decided that we didn’t need to (change it)," Eggington added.
I found this on the Alpha Tauri's AT02 website, not sure if anyone else has seen it...
The chassis is the core element around which the entire car is built, with the driver's survival cell at its heart.
Attached to the chassis are all the other major components; power unit, transmission, suspension, bodywork, wings, and the floor.
Designed and built entirely in-house, it is homologated after passing stringent pre-season tests.
The gearbox and rear suspension come from last year’s Red Bull Racing car, while we have completely redesigned the front suspension.
A lot of online articles are purporting that Alpha Tauri didn't take the "free upgrade" but their own website states they are using last year's RB gearbox and rear suspension.
