Central Driving Position
Think of the world’s ultimate performance cars: Formula One™ machines. What do they have in common? A central driving position (CDP). The primary reason isn’t, in fact, reduced weight. It’s balance and control. Putting the driver in the center of the vehicle means vehicle response and driving dynamics are exactly the same in left and right-hand turns. Immediate, exquisite and reassuringly consistent.

Unless you’ve driven single-seaters before, you can’t appreciate just how much you unconsciously compensate for the difference in handling and sight lines between one type of turn and another in traditional cars. Just as important is the Pléthore’s central engine location. Most supercars claim to be mid-engine when in fact they are mid-rear-engine designs; their engines are located behind the centerline of the vehicle. Thanks to its true mid-engine configuration, the Pléthore achieves unrivalled balance and performance.

Ideal Weight Distribution
For years, supercar experts have spoken of 50/50 as the ideal weight distribution. But left-to-right weight distribution is only part of the story. The ideal supercar would be perfectly balanced front to rear and side to side. And it would retain that balance with or without the driver and regardless of fuel load.

That is exactly what we have achieved with the HTT Pléthore. Placing the driver in the center of the car means the car remains balanced in every axis, even with the driver in place. And the central location of the twin fuel tanks means the car’s balance remains virtually the same regardless of fuel level.

Three-Seat Configuration
The emgineers of the HTT Pléthore has carefully placed the passengers on either side of and slightly behind the driver.

This allows for superior driver comfort, lateral visibility, and racecar-like control.

The exhilaration of a solo, dual or three-person ride in this vehicle, on public motorways, is a nirvana few will ever experience in their lifetime.

Scissor Doors
The iconic HTT Pléthore scissor doors are designed for both beauty and convenience. Remote-controlled, lightweight, graceful, and smooth, they open dramatically, but even more importantly allow for comfortable entrance and egress, even in narrow spaces.

Just click the key fob and the doors open and close automatically. In a car that offers a significant variety of powerfully graceful features, the stunning visual appeal will appeal to anyone seeking a change from what most supercar manufacturers offer.

Carbon Fibre Construction
Vehicle design changed forever with the advent of carbon-fibre construction.

Today, every Formula One™ chassis features carbon-fibre monocoque construction for optimum, safety, rigidity and torsional strength at previously unattainable low weight.

So does the HTT Pléthore.

With both a full carbon-fibre body and monocoque chassis (most of the body panels provide structural support), HTT has optimized the weight/safety paradigm.

Safety is further enhanced by the Pléthore’s reinforced carbon-fibre roof and integrated tubular roll cage.

Aerodynamics
In the HTT Pléthore, aerodynamics are of paramount performance. Consider the car’s staggering 247 MPH top speed. Faster than every Formula One™ car, faster than the fastest cars competing at the 24 Hours of Le Mans. At top speed, the Pléthore covers a mile in less than 15 seconds. So it’s critical not only that the body design have a low coefficient of drag, but also contributes greatly to the car’s stability.

The Pléthore is designed to do that in a number of ways: Computational fluid dynamics (CFD) and on-track testing have provided an optimized aerodynamic design and downforce while keeping a low drag coefficient. The Pléthore’s sealed flat bottom and rear diffuser reduce turbulence underneath the car and minimize the wake behind it. These, in combination with other design features, produce downforce at both ends of the car at speed.

Powertrain
HTT have intimately cooperated with Pratt & Miller, a premier American performance engine and gearbox developer, to create a powerful integration of these critical components. The HTT Pléthore’s engine is a supercharged aluminum alloy V8 based on an international-race-winning design.

The gearbox is a robust sequential shift transaxle with both a conventional electronic shifter and F1™-style steering wheel paddles. In paddle-shift mode, shifts are lightning fast – faster, in fact, than can be achieved manually. This, combined with significantly reduced mass, reduces friction, provides long service life, eases maintenance and optimizes weight distribution and power.

Suspension
An advanced carbon-fibre monocoque is the ideal platform upon which to attach the HTT Pléthore’s racing derived double wishbone suspension at all wheels.

The primary suspension components are made of high-strength aluminum for maximum performance and minimum unsprung weight.

Like Formula One™ teams, HTT uses sophisticated vehicle dynamic software to optimize damping, springing and suspension geometry, then validates the gains through extensive on-track testing.
