Overall
Extremely positive sentiment focused on the vehicle's engineering, design, and emotional appeal. The community feedback is dominated by admiration for its powertrain, specifically the naturally aspirated 8.3L V16 engine developed by Cosworth, which is described as sounding "incredible," "violent," and like a "proper race motor." The hybrid system, combining the V16 with three electric motors for a total of 1,775 hp, is noted as a significant technical achievement. The interior is frequently praised as a "masterpiece" and "timeless," with particular appreciation for its analog, watch-inspired gauge cluster and lack of screens.
