The iPace would rival the Model X. The iPace is FAR behind the Model X in all performance measures. The iPace has a manufacturer's estimated range of ~350km, no EPA rated range given. The Model X has EPA rated maximum range of 475km - that's a third party verified range that is 125km above the estimated (and very optimistic) range of the iPace. As far as speed goes, iPace is 4.8s to 100km/h, while the P100D variant of the Model X is 0 - 100km/h in 3.6s, a solid second faster.
