28‑lb Motor Stuns EV World
A new 12.7-kg (28‑lb) electric motor now claims over 1,000 horsepower and reportedly out-powers a Tesla Model S Plaid on power density — a striking benchmark for EV compactness and punch [].
[YASA announced]yasa.com on October 22, 2025 that a 12.7‑kg prototype produced a 750 kW (≈1,005 hp) short‑term peak and delivered an unofficial power‑density benchmark of 59 kW/kg, with YASA estimating continuous power in the 350–400 kW range. yasa.com The new 12.7‑kg unit improves on an earlier summer 2025 prototype that weighed 13.1 kg and produced 550 kW, a roughly 40% increase in peak power density reported by YASA. yasa.com YASA operates as a wholly owned subsidiary of Mercedes‑Benz after the automaker’s July 22, 2021 acquisition, and the company said the prototype uses no exotic materials while being targeted at high‑performance programmes such as AMG and compact in‑wheel applications. businesswire.com Tesla’s official Model S Plaid spec lists 1,020 hp peak on Tesla’s site, and YASA emphasised its 750 kW figure came from a dynamometer short‑term peak rather than a continuous, in‑vehicle output rating. tesla.com
