Automotive WI - GM Europe equivalent of Pontiac Fiero

In OTL the rise of the Hot Hatch segment in Europe from the 1970s-1980s+ caused sales of front-engined RWD coupes like the Ford Capri and Opel Manta to decline to the point they were replaced by less than adequate models such as the front-engined FWD (2nd gen) Ford Probe/Cougar and Opel Calibra.

What-If however GM Europe instead sought to indirectly replace the Opel Manta with a mid-engined sportscar akin to the Pontiac Fiero from the late-80s to early-90s, powered by 136-156+ hp (up to 201+ hp) 2-litre DOHC GM Family II and 168-244+ hp 2.5-3.2+ GM 54-degree V6 (or less likely a Euro-adapted 157-202+ hp 2490-2986cc DOHC version of the GM 60-degree V6) engines?

3.8L SC goodness

In 1991, the Earlier Series I 3800 was around in SC form, still 205HP

Very respectable for the time, and reliable

Euros love Turbos, Right?

So there is this from Buck from 1985 onwards

245hp, that would take a little more effort in stuffing in a Fiero, but doable

However both the Family II and 54-degree V6 engines already had the benefit of being produced in Europe by GM, whereas the above engines are unlikely.

That said, could see an ATL thriving Vauxhall that remains separate from Opel a bit longer (and merging with the latter on its own terms) easily making use of an early/mid-70s 2.5-3-litre version of the 60-degree V6 (slotting above the Vauxhall Slant-4 and Slant-4 derived V8 engines in the event the latter reached production). The 60-degree V6's output in initial non-US emissions de-restircted OHV form would made it comparable to Ford's own Euro-spec Cologne/Essex V6s using the later OTL Chinese-spec 145-170 hp 2490-2986cc LB8/LW9 versions of the 60-degree V6 as a rough guide.
 
Not sure how accurate the following is though interesting the 3350cc GM 60-degree V6 LQ1 Dual Twin Cam was actually capable of 275+ hp (reputedly up to an honest 281 hp) instead of 200-215 hp were it not for the lack of a suitable FWD automatic transmission, since it translates to an ATL Euro-adapted 157-202+ hp 2490-2986cc V6 being potentially capable of putting out 204-250 hp at most which compares well with the 168-244+ hp 2.5-3.2+ GM 54-degree V6. - http://www.angelfire.com/ca2/34Performance/dohc.html

The closest thing to a post-90s GM Europe equivalent of the Pontiac Fiero with such a V6 would be an ATL production version of one of the Ford Maya concepts by ItalDesign.
 
It would be called the Opel Speedster/Vauxhall VX220.

The intention being such an ATL car would precede the Lotus Elise-based Opel Speedster/Vauxhall VX220 by roughly a decade or more from the late-80s to early-90s, being akin to a Toyota VZ/MZ V6-powered mk2 MR2 with a similar production run (a V6 mk2 MR2 appears to be a fairly common engine swap).
