1993 Alfa Romeo RZ

Yesterday a local automotive designer stopped by to say hi and to see what was going on in the CICFS garage (Milano close-ratio transaxle build, Maserati heater core swap). He brought his Dodge Viper. Base engine offered up from the contemporary heavy-duty Ram, Chrysler's newly acquired Lamborghini division was tasked with tapping into the V10's potential. A monster was born. The RZ, known as Il Mostro may not stack up to the specs of the Viper in terms of performance, but it stems from a similar corporate exercise; bringing a show car and its spirit to life in a series production vehicle.

The basis of the two vehicles could not be more different. Chrysler dove deep into the weeds, tooling up new cylinder heads and more for the engine, devising a new chassis, and putting together many of the car's mechanicals from scratch. Alfa, in creating an arguably wilder monster, dipped into its current parts bin, repurposing the DeDion / transaxle chassis of the Milano. Front double wishbone torsion beam suspension with coilover helpers, rear DeDion suspension, and a transaxle with inboard brake calipers. The V6 was a modestly hotter take on the 3.0L in the Milano.

We only worry about the RZ/SZ specific components when it comes to keeping one of these on the road. There are very few of those when it comes to mechanicals - headers and coilers come to mind. Bodywork, on the other hand, is likely in short supply. Fortunately, this example looks very clean and complete and shouldn't require month-long eBay searches for anything short of a collision.

With the SZ, you're plunking down serious cash for a design exercise. An exercise that, to our eyes, was not an improvement on existing Alfa Romeo transaxle offerings. Still undeniably cool, the high valuations lend the RZ/SZ pair their new status as more of a collector car, as opposed to a true enthusiast car. And, if you're more of a collector? You might as well seek out a low-mileage example such as this RZ.
