Beautiful!! Now do one from a Sunbeam Tiger.
Thanks Evan! As for the Sunbeam
Tiger, that
has to remain a convertible! Instead, a scenario ...
In the RW, the Rootes Group approached Ferrari to supply a V8 to power a '
Super Alpine. The obvious candidate was a mass-produced version of Ferrari's
Tipo 205/B V8 - a 90°, 1.5 L (91 cid) engine. Quite sensibly, Ferrari refused to commit to supplying in comparatively large numbers what was effectively a hand-made engine.
So, what if Rootes didn't want to merely compete with AC. Instead, they wanted a '
Cobra Killer'. Forget Ford's 260 cid (4.2 L) iron-block boat-anchor. How about an aluminium BMW V8 instead?
What-If: Rootes-Sunbeam Introduce BMW Aluminium V8s in 1965Negotiations with Ferrari were looking unproductive but some bright-light at Rootes noted the trouble that BMW had created for itself with the US-aimed BMW 507 grand tourer. By 1965, the aluminium BMW V8 was due to be replaced by the more economical 6-cylinder BMW M30. (This 'old' V8 had the same arrangement as the Buick 215 cid V8 then just taken-over by Rover - ie: the BMW was a push-rod OHV V8 with aluminium alloy block and heads construction.) After a quick-and-dirty prototype conversion (the 'BMW-Alpine'), Rootes offered to buy rights and tooling for the M532 V8 engine from BMW.
Priority was adapting the German engine to UK production standards (with Imperial fasteners, etc.). The BMW stroke of 2.95 inches (75 mm) was retained but bore was slightly increased to 3.25 inches (82.55 mm instead of 82 mm). [1] The result was a 195 cid (3,208 cc) V8 in Imperial measures. For the Sunbeam range, the high-lift cams from the earlier M507/1 engine were restored. [2] The resulting V8 produced 170 hp at 5,600 rpm - which compared well with AC's Ford 260 V8 producing 164 bhp at 4,400 rpm. More importantly, aluminium alloy construction meant that the Rootes 195 weighed only 325 lbs compared with over 480 lbs for the iron-block Ford.
What-If Sunbeam Alpine and Sunbeam Tiger Series Vs Line UpThe Sunbeam
Alpine for 1965 held over the old Rootes 1,592 cc (97.1 cid) 4-banger but with a slight power increase due to adopting a Zenith 36 NDIX 2-barrel carburettor. The new Sunbeam
Tiger introduced the Rootes 195 cid aluminium V8 engine. Twin Zenith carbs dictated a central hood scoop (both for induction and extra 'head space') but, otherwise, the
Tiger was indistinguishable from the
Alpine sports car.
In 1966, Sunbeam introduced the
Alpine Series V. This sports car featured an entirely new, 1.6 L (97.5 cid) aluminium-block 4-cylinder engine - effectively 'half' of a 3.2 L V8. The rest is history ...
