Its actually the same answer for both of you. Emissions "fleet averaging" occurs across direct ownership business units, not just single brand. So Ferrari is offset by Fiat, for example, even after the partial divestiture. Lamborghini is offset by VW.
Lotus is in a weird situation because they aren't owned by another car brand that does business in the US market. Volvo doesn't count because they are a separate investment of Geely, they don't act as either a parent company or as a peer brand within a single corporation. Lynk &Co would probably qualify, but they aren't sold in the US. So Lotus is "on their own" for purposes of emissions regulations.
