The “WxB” package adds a more aggressive exterior with unique bumpers, dark or blacked‑out accents, LED headlights, and alloy wheels, plus a more premium interior with better upholstery, leather‑wrapped trim, seat heaters, and extra comfort/convenience features. Depending on year and market, it typically includes safety tech such as Toyota Safety Sense (with features like pre‑collision braking and lane departure alert), multiple airbags, ABS, and stability control, making it both efficient and well equipped.
