TVR Tuscan Speed ​​Six: A Complete Review

The TVR Tuscan Speed ​​Six first went into production in the early 2000s. The car has an innovative removable hardtop that stows neatly in the trunk along with the removable rear window, leaving enough room for two suitcases. decent size (or a couple of golf bags). Although the curb weight of the car is only 1000kg, conveniences such as air conditioning and power steering are still included. TVR’s own engine, the infamous Speed ​​Six, is installed under the mechanically fastened hood cover. Over time, TVR included speed six in all Tuscan derivatives in different melody states:

  • 3.6 liter Mk1 – 350 BHP and 290 ft.lbf
  • 4.0 liter Mk1 – 360 BHP and 310 ft.lbf
  • 4.0 liter Mk1 Red Rose – 380 BHP and 310 ft.lbf
  • 4.0 Liter Mk1 S (Before 2003) – 390 BHP and 310 ft.lbf
  • 4.0 liter Mk1 S (post 2003) – 400 BHP and 315 ft.lbf
  • 4.0 liter Mk2 (post 2005) – 380 BHP and 310 ft.lbf
  • 4.0 liter Mk2 S (post 2005) – 400 BHP and 315 ft.lbf
  • 4.0 Liter Mk2 Convertible (Post 2005) – 380 BHP and 310 ft.lbs

In contrast to modern vehicle design techniques, TVR did not use any computer software, instead the shape of the vehicle was shaped by a team of TVR stylists, led by Damien McTaggert in close cooperation with Chairman Peter Wheeler. In total, it took two years to finalize the way of stunning the vehicles.

Designing a car in this way is time consuming, however it does offer certain advantages; Rarely is it possible to control a surface on a computer as subtly as when sculpting by hand. it is commonly recognized that tooling for mass-produced vehicles takes longer to develop than the design of the car itself; this is categorically not the case for a car designed by TVR.

Many of the features found on the car, features that make the car so extraordinary, are included for engineering reasons, but serve to enhance the overall appearance of the vehicle. As an example of this, the unusual arrangement of the hood (the main hood cover is bolted to the car) forms a slightly stressed member that allows the engineers to channel the airflow very precisely. Also, the absence of hinges and gas struts means that the bonnet cover can be made to be very light.

In simple terms, it can be deduced that the exterior of the vehicle contrasts extravagantly and complements the interior, which has a relatively minimalist concept. Function has once again followed form and the interior components are of the highest quality. an example of the interior function can be seen in the curved aluminum dash top that acts as one of the car’s reinforcing crossbeams.

An example of the original thinking of TVR’s designers has manifested itself in the instrument binnacle that is manufactured in-house. The original design allows for a link between the logbook and the engine management system, which with its wide range of sensors monitoring various engine parameters, allows a wide range of data to be displayed to the driver. Readings can be easily selected via a brass rotary knob, allowing the driver to easily access the various data readings the vehicle has to offer. Available data sets include fuel level, oil level, oil temperature, highway speed, battery voltage, fuel pressure, ambient air temperature, and engine speed. An additional feature is included on top of the instrument binnacle in the form of graduated shift lights; the lights can be adjusted to communicate to the driver their preferred engine speed, allowing them to change gears at a sweet spot in the engine’s rev range.

TVR’s design engineers spent a lot of time developing the car seats. Many TVR owners choose to test their cars’ full potential on the race track. To that end, and because built-in height adjustment is impractical in a car of this type, the seats have removable backrests. This allows the driver (and passenger) to sit lower in the seat, providing ample room for occupants to wear crash helmets.

The styling of the car has been influenced by the design and configuration of the engine. TVR’s approach, with the engine at the front and the driving of the rear wheels, allows the use of the most classic engines of sports cars: the six-cylinder in-line. As a side note, TVR doubled down on Speed ​​Six to create the incredible Speed ​​Twelve.

One of the main characteristics of an inline six cylinder is that it can be perfectly balanced. TVR has chosen to use a completely aluminum construction with important innovations that move away from the traditional mold used by the company’s engineers. It is the first TVR engine to employ four valves per cylinder, allowing for greater volumetric efficiency at high revs, giving the engine a sportier nature. Finger followers allow for greater valve acceleration, improving engine torque. The two chain-driven overhead camshafts ensure a quiet and reliable drive. The engine sits very low in the car’s chassis to promote a lower center of gravity, enhanced by a 15-degree engine rake that allows the hood to sit even lower. The engine’s designers have achieved such a low CoG by using a dry sump system, similar to that of the Speed ​​Eight and Speed ​​Twelve racing variants. The engine features steel connecting rods lined up with lightweight slipper-style pistons and a nodular iron crankshaft.

The vehicles chassis is based on a shorter version of that found on the Cerbera, providing more room than would be found on a Chimaera or Griffith. The overall dimensions of the chassis have been derived from the Tuscan Challenge race car. The benefit of using a race-proven chassis is immediately obvious, for one thing, rarely has a vehicle’s chassis been tested so thoroughly. The roll cage, door beams and aluminum cross-brace beams are evidence of TVR’s commitment to safety, something that has been at the forefront of the design process from the start.
