Despite its performance data almost matching the others, the Escort never feels as fast, maybe due to its engine’s civility.
But its handling is safe and predictable, with some body roll, excellent grip and initial understeer that transitions to easily catchable oversteer (usually tempered by a spinning inside rear wheel).
Only braking feel, which lacks bite and progression, saps confidence at higher speeds.
If you want the starkest contrast between ‘our’ three cars, you only have to step out of the Ford and into Stephen Crothers’ Sunbeam Lotus.
This Talbot Sunbeam Lotus has a non-standard, power-assisted rack, making it feel even more agile
Chrysler, née Rootes Group, launched the Sunbeam range in 1977 to replace the long-serving Imp.
Its European business had been kept alive thanks to massive UK government support, which demanded a commitment to the Linwood factory in Scotland where the Sunbeam was to be built.
Based on the Hillman Avenger platform, the Roy Axe-designed three-door hatch enjoyed a positive reception and soon got a performance lift with the Sunbeam 1600Ti.
But that was just a teaser for what was to come.
The Talbot Sunbeam Lotus is powered by a 220bhp Twin Cam motor
Chrysler Competition Department’s Des O’Dell had seen first Ford then Vauxhall making hay in the WRC with, respectively, the Escort RS 1800 and Chevette HS; he wanted a piece of the action and commissioned Lotus to achieve it.
Hethel’s solution was to take its 16-valve, 2-litre Type 907 slant-four and develop it into something more gutsy.
With capacity boosted to 2172cc, the engine was re-coded Type 911 and, mated to a five-speed ZF ’box, crammed into the Sunbeam.
Outputs of 150bhp at 5600rpm and 150lb ft at 3800rpm were enough for some pretty serious performance from the 960kg hatch: 0-60mph took 7.8 secs, while a top speed of 122mph beat both our rivals.
This Talbot Sunbeam Lotus sits on non-standard Compomotive wheels
To accommodate a near doubling of output versus the 1.6 GLS on which the Lotus was based, the suspension was lowered and stiffened, with the work carried out at Ludham Airfield in Norfolk, near to the Lotus HQ.
Revealed at Geneva in 1979, shortly before Chrysler Europe was bought by PSA, which renamed the business Talbot, the Sunbeam Lotus may have been late to the homologation party, but by 1980 the works rally cars were fulfilling O’Dell’s expectations.
Henri Toivonen and co-driver Paul White won the RAC Rally that year, and by the end of 1981 Talbot had secured the manufacturers’ title.
The Talbot Sunbeam Lotus has a firm ride but little body roll
Meanwhile, the roadgoing model was cosmetically refreshed in line with the rest of the Sunbeam range, gaining larger headlights and a new grille; the Lotus version was fitted with snazzy Marchal spots above the front bumper, and it got the option of Moonstone Blue paint with silver stripes in addition to the series one’s default black-with-silver livery.
A few caveats are needed before describing how Stephen’s Sunbeam performs.
Its Lotus Type 911 is running bigger valves, high-lift cams and high-compression pistons, which, he estimates, is yielding around 220bhp.
The gearbox has also been rebuilt to works spec, and the steering rack has been swapped for an electrically power-assisted item from, of all things, a Vauxhall Corsa B.
The Talbot Sunbeam Lotus has a simple cabin; this one has a non-standard driver’s seat
There are also AP Racing calipers and pads, and discs instead of drums at the rear.
Which all makes sense, since Stephen had planned to do some hillclimbing with the car, but with Sunbeam Lotus values rising, he’s having second thoughts.
Either way, it makes for an intense driving experience.
Setting aside the non-standard steering, the Sunbeam is far and away the tightest-handling of our trio.
The Talbot Sunbeam was a mundane base for a potent rally star
Its granite-like body control goads you into ever-more ambitious cornering speeds, reinforced by the tenacious grip of modern rubber (although it’s the only car here with a limited-slip diff, so you need to be quick to catch the rear when it breaks free).
The brakes feel dead until worked hard, then they comfortably outperform the Vauxhall’s.
The ZF five-speed changes with a lovely mechanical precision, while 24mph per 1000rpm in top gives a sensible cruising gait.
Not that you’d use it often: the ferocious bark from the Lotus Twin Cam turns into a full-blooded, Dell’Orto-fuelled bellow as you pitch for the redline, and it soon becomes addictive.
The Vauxhall Chevette HS has a scruff-of-the-neck feel
As a point-to-point B-road blaster, it has the other two well and truly licked.
Is there an obvious winner, though? The Sunbeam feels marginally sharper than the Vauxhall, but it demands more concentration to exploit its finely honed dynamics.
The Escort stands alone due to its milder manners, but in the real world its absolute performance almost matches the others – it just sounds and feels as if it doesn’t.
Which leaves the HS as the perfect bridge between the ballsy, knife-edge Talbot and the ultra-composed Ford.
