The Infiniti Q60 runs across two entirely different platforms under one nameplate — and a cover ordered without knowing which generation you own will not fit correctly. The V36 Q60 (2014–2015) is a renamed G37 Coupe at 183.7 inches long and 72.2 inches wide. The CV37 Q60 (2017–2024) is a ground-up redesign: 183.3 inches long but 1.0 inch wider at 73.2 inches, with a different front fascia profile, C-pillar curvature, and rear deck geometry. There is no 2016 Q60 — the model year was skipped entirely in the US market. Convertible buyers face an additional variable: the Q60 Convertible's power soft-top stows at the rear deck, raising the profile by four to five inches and causing a standard coupe cover to tent at the rear.

DaShield covers are selected by vehicle, generation, and body style — so the cover matches the body you actually own. The Vanguard UHD handles outdoor parking with 5-layer woven construction and a 5-year warranty. SoftTec Satin protects garaged Q60s from scratch and dust in storage. Both are Designed in Buena Park, California.

Three priorities drove the Ultimum's design: lateral energy dispersion under point-load impact, all-weather outdoor durability for vehicles that park outside year-round, and a fit precise enough to maintain body contact during storm conditions.

The first priority — energy dispersion — is addressed by the multi-layer woven construction. Each woven layer adds a lateral force-transfer pathway. More pathways mean more of the hailstone's kinetic energy distributes across the fabric surface before reaching the panel below. The Ultimum does not carry a numbered layer count in its name because the construction is a continuous woven assembly, not a stack of discrete sheets. The architecture is the protection.

The second priority — outdoor durability — is addressed by the waterproof barrier integrated into the woven assembly and the UV-resistant yarn treatment. A cover that degrades in its first season of sun and rain exposure is not a permanent outdoor solution. The Ultimum carries a Lifetime warranty because the materials are rated for continuous outdoor exposure, not periodic use.

The third priority — fit — is addressed by vehicle-model-specific patterning. The Ultimum at $209 for car fitments is not a universal-fit cover. It is patterned to hood geometry, trunk profile, mirror dimensions, and rocker panel length for the specific vehicle. Fit determines whether the cover maintains surface contact during wind-driven hail. A cover that billows or gaps at the quarter panel has reduced the lateral dispersion mechanism at exactly the moment it matters.

These three properties are not independent. A cover that disperses energy but does not stay on the car during a storm has failed at the system level. The Ultimum is designed as a system.
