The 1966 Triumph GT6. Winning formula.

Standing still the GT6 looks beautiful - but impatient for the off. The 1998 cc engine develops 95 bhp. and that's a lot of power to keep poised under your foot.

Have a test-drive, turn the key — and just over 7 seconds later you'll be doing 46 mph in 1st! Follow up with top gear figures like 40 to 60 in 7.5. 50 to 70 in 8.5 Fierce acceleration that the GT6 takes in its smooth, 6-cylinder stride. It takes sound engineering — and 6 cylinders - to make an engine that stays smooth whether you're idling along in top, or accelerating to 96 mph in 3rd.

The GT6 takes its breeding from the Triumph Spitfires that took first and second places in their class at Le Mans. The biggest difference is the engine. It's bigger. But the body, chassis, independent suspension and front disc brakes are all closely related to the Spitfire. They offer race-winning stability, road-holding and braking. Performance that makes the rally driver sure of himself and his car. The GT6 engine was born at Standard-Triumph, which is exactly the right place for a winner to be born — witness the string of rally successes from Le Mans to Sebring.

1966 Triumph GT6 Performance Specifications

All GT and comfort.

Start with the seats. Welcoming - they make the GT6 an invitation on 4 wheels. Soft to sink into, tall to support you, and shaped to hold you firm on corners. Both are easily adjustable forward or back and the steering column also adjusts. There's a leather covered racing style steerina wheel. deep-pile carpet underfoot, PVC leather-cloth on the parcel shelf, door waist rail and around the facia.

The instruments are grouped to be read at a glance and are set in a veneered panel. The temperature and fuel gauges are centrally mounted. Warning light for the main headlamps is in the speedometer. The oil pressure light is in the tachometer.

The GT6 has an 107 mph shape.

When the GT6 is in full flight, every line, every curve, from the flush-fitting headlights to fastback seems to be urging it on. Yet amidst all the glamour of speed, the GT6 relies on one down to-earth fact. Sound, race-track proved, Leyland engineering. This is the car that's reliable as it's fast, safe as it's volatile.

Performance The GT6 knows the ways of today's world, it gets there quickly. O to 60 in 11.1 to be precise. Through the middle speeds, safety is allied with satisfaction. Top-gear times like 40-60 in 7.5 cut overtaking time so dramatically that the extra margin of safety can be measured in seconds.

Safety The panoramic windscreen is made of sately class and the steering column is designed to telescope on serious impact, without coming forward. The doors have anti-burst locks. More safety factors, padding around the facia and grab handle, twin screen washers, two speed wipers, and two-tone horn. All independent suspension gives stability on corners, road-holding grip. Front wheel disc brakes give you extra rliability on the wet, and remain free from fade even after continued heavy braking. The GT6 has a forward-hinged bonnet that cannot fly up while the car is on the road. When you think about safety, GT6 is a reassuring thought.

Here's where the suitcases stretch out.

GT6 drivers and passengers have lots of room, so why shouldn't the suitcases? The luggage area measures 42in wide by 41 in deep or three suitcases. The rear door is 34in wide. Additional accommodation, a parcel shelf beneath the luggage platform. This is one sports car where luggage isn't limited to tooth brush and comb.

On the right, a filmed trailer for the GT6 To enjoy the performance, in full-colour and 3-dimensions, contact your local dealer and arrange a test-drive.

1. The GT6 has a maximum retardation of 1.0 g. Equivalent to stopping in 30ft from 30 mph. There are disc brakes at the front, where 70% of the braking effort is developed.

2. All-independent suspension offers road holding to match the power.

3. Beneath the streamlined, lightweight body there is a heavyweight strength. The chassis has a double backbone and out-riggers, made from channelled steel girders. And if you need to tow, the GT6 has strength to spare.

4. Compared with its nearest rival, the GT6's turning circle is smaller by 7 feet!
