Distinctions - The feature suite for the Hot Wheels Audi ‘90 Quattro consists simply of two points; a bright and colorful livery complete with original sponsor designs, and the ability to roll smoothly and consistently in a straight line. However, this is more than enough for most kids looking to play or the average collector looking for a scale model.

Criticisms - The nature of a 1/64 scale makes finer details harder to consistently print and paint, so not all details will be 1:1. The Hot Wheels Audi ‘90 Quattro maintains proportions fairly well, though some dimensions will not be true to the full size model, with a notable shift from the deep-set wheels of the original being changed to a more turbofan-esque design for the Hot Wheels Audi ‘90 Quattro.

Distinctions - Die-cast material is durable, maintaining proportions with wear and environment. Print colors in the Hot Wheels Audi ‘90 Quattro are vivid and maintain their saturation well even with wear. Axle and wheels provide low-friction rolling for speed through tracks and on a variety of surfaces.

Criticisms - Prints have some bleed, with edges often blurring on smaller, more precise decals. Paint protective coating is thin, with notable blemishes appearing after light use. Die-cast, while more durable than some plastic elements, is fairly thin, with breakage possible under concentrated pressure from even human weight. With more painted elements than other, less race-oriented models, the Hot Wheels Audi ‘90 Quattro is sightly more vulnerable to damage affecting overall aesthetics.

Distinctions - The Hot Wheels Audi ‘90 Quattro captures all of the major points of its full-scale inspiration with no excess. Particularly notable compared to other less-unique Hot Wheels models are the inclusion of the aggressive front intakes and huge side-port exhaust, both of which are major factors in the character of the original. Prints and colors are crisp and visually appealing.

Criticisms - Print bleeding and piece quality of wheels and tires prevent the Hot Wheels Audi ‘90 Quattro from being truly 1:1. A notable adjustment away from the original IMSA wheels to more turbofan-looking wheels is not necessarily aesthetically displeasing, but is less accurate to the model most will remember.

Distinctions - The Hot Wheels Audi ‘90 Quattro is generally fairly sustainable, being composed of fairly recyclable parts accentuated by relatively strong durability with normal and expected use. Combine this with a considerably active secondhand market for collectors and hobbyists, and the car’s lifespan is fairly predictably sustainable.

Criticisms - Plastic and die-cast components are not as durable as real-life materials. Similarly, axle damage can render the entire Hot Wheels Audi ‘90 Quattro inoperable for play or display.

Distinctions - Hot Wheels ubiquity makes finding accessories like track or trick pieces, whether Hot Wheels branded or not, incredibly easy. The low up-front cost makes it incredibly accessible to almost any demographic. In addition, representation of more specific/niche vehicles like the Hot Wheels Audi ‘90 Quattro are few and far between from other manufacturers, making, albeit by default, Hot Wheels the go-to.

Criticisms - Larger scale models may offer more accurate representations of the Hot Wheels Audi ‘90 Quattro that would better befit the picky or particularly discerning collector.
