TVR Sagaris

The TVR Sagaris began as a plan to create a racing version of the T350 that would be an ultimate trackday car in ‘road trim’ but, with the minimum of modification, be a race winner by having ‘all the right bits’ already in place.
Looking at the bodywork, the pretty T350 lines have mutated into a shape that exudes attitude – and no exterior body panel is shared with the T350 anymore. Starting with the roof, the driver’s side is raised to accommodate a crash helmet. The front and rear of the car feature stylized spoilers and splitters to guide and control airflow for downforce. The sculpted front and rear wing surfaces retain the shape of the vents featured on the 2003 concept car but the vents are closed to strengthen the wing and prevent the exit of road spray and stones on to the windscreen. The central bonnet panel releases heat from the engine. Finally, the body mounts have been moved up on the chassis rails so the body sits some 25mm lower than a T350. Stationary or in motion heads turn and camera phones are pointed – the Sagaris is a dramatic car from every angle.
Open the door and enter the car for the first time and the results of the quality improvement programme are immediately apparent as you close the door and take the helm, sitting in a TVR-made and custom trimmed racing seat. It feels solid and the driving position is low and comfortable. Adjustable reach and rake on the steering column and [optional] electronic lumbar adjustment allow you to tailor the driving position to suit you. Start the 406bhp 4.0 litre TVR Speed Six engine and you get a sense of the potency that backs up the promise of the aggressive styling. The stainless steel side exit exhausts bark with an engine note unique to the Sagaris – you can’t resist blipping it, probably with the window down!
On the move the ride is tightly controlled – remember this is a car biased for track use – yet the Sagaris will easily ride bumpy city streets and B roads without fuss. It feels plan ed, even at low speeds. The steering rack is fast and precise at 2.0 turns lock to lock, with electro-hydraulic power assistance. This is the point of revelation with a Sagaris – the wild looks and headline power output of 406bhp may intimidate, yet first impressions are that this car inspires confidence from the moment you move off. And it gets better the faster you go.
Driving on the wave of torque at around 3,000 – 4,000 rpm, you can make very rapid yet quite relaxed progress. But, like all TVRs, there is another side to this engine that comes alive when you press the gas pedal harder. Peak power is between 7,000 and 7,500 rpm and visiting this area of the rev range reveals the Speed Six’s heritage as a GT race winning, Le Mans motor. The brisk Mr Hyde can become the manic Dr Jekyll at the behest of your right foot. The chassis of the Sagaris is beautifully resolved to feed all this torque and horsepower into the tarmac and exiting 2nd gear corners – even in the wet – can be a tidy affair.
The TVR development team is justifiably proud of creating a chassis that is extraordinarily accomplished on a racing circuit and genuinely nice to drive around town. The modifications to make a Sagaris into an out-and-out racecar are minimal but for trackday-goers it’s close enough to a racer without becoming unpleasant on the road. Returning to the original plan, the Sagaris is “mission accomplished”.

The TVR Sagaris. Few cars look as dramatic as the new TVR Sagaris. While motorsport is never far from TVR’s designers’ and engineers’ minds, the rigorous demands of the endurance racing arena were also a priority in the Sagaris concept.

It has been designed to be the ultimate racing car for the road. Now it is possible to know what it feels like to drive a Le Mans car everyday. Every scoop, every vent might add to the most extraordinarily dramatic lines, but they are all there for a distinct purpose.

Lightweight is much talked about by car manufacturers but is rarely achieved in combination with enormous power. Thanks to the rigid tubular steel chassis and extremely light composite bodywork, the Sagaris comes in at just over a tonne. With low drag and downforce producing aerodynamic features at both the front and rear of the car, the styling of the Sagaris works just as well as it looks.

The Sagaris is propelled by the same four-litre 380 bhp engine as the Tuscan S. It is docile in town where it can burble along at low speeds in high gears. But press your right foot into the carpet and you are pushed back into the seat, as the engine howls its way to a red line close to 8,000 rpm. Statistics can be dramatic. 0-60 in 3.7 seconds certainly is.

Following extensive research and development in conjunction with fellow experts at Bilstein, the Sagaris’ suspension and handling are profound, with unprecedented capabilities. Combined with its rigid tubular steel rollcage and wider track, the Sagaris manages to be an enthralling, hair-raising drive, but a safe one, too.
