Description
Would you all believe this was something did in the time gaps before my environmental economics class? This was just another random idea I had. I guess mostly inspired from the large trucks I have to drive next to commuting to and from classes everyday. Unfortunately my brain has run out of time and energy to do the interior for this as finals are coming up. Of course constructive feedback on how to improve future drawings is always more than welcome!

SMA Elephant 6200 SC

In short: Large commercial haulers are a necessity in transporting goods. However many semi trucks on the road today still only achieve roughly 5mpg due to very fuel hungry engines and aerodynamically inefficient designs. Although still somewhat traditional looking, the SMA Elephant concept carries several features that could significantly save on fuel and repair costs without sacrificing load capacity.

Engine/powertrain:
model shown- A single 300hp diesel turbine connected to an electric generator/clutch. The electricity produced by the turbine powers a single 300hp equivalent electric traction motor capable of producing 2,530 ft-lbs (3,430 N-m) of torque. At speeds above 30mph, the generator can act as a clutch, connecting the turbine directly to the drive motor, allowing the turbine to send energy directly to the rear wheels as well.

other models- special order models can be equipped with 500hp, 700hp, or even 1000 hp equivalent power turbines and motors in singles or multiple units depending on the application.

Curb Weight:
model shown- 12,532lbs (5,684 kgs)
other models: custom order models can weigh 15,000 lbs, 17,000 lbs, or more depending on the intended application

Load Capacity:
model shown: 150,000lb (68,039 kg) combined weight, if legally allowed
Specialty models can be equipped to handle +300,000lb (136077 kg) combined loads

Other Notable Features:
Active aerodynamic shutters- the slots on the grill, hood, and brake ducts can close during normal highway cruising to reduce drag or open to provide additional cooling when needed.

Active aerodynamic pneumatic jets- A compressor fan powered by the main turbine operates a network of air ducts that draw air away from key locations of high pressure in the front of the truck and redirect that air to fill in key areas of low pressure in the rear of the truck. Trailers could easily be fitted with pneumatic tubes that could also bleed high pressure air from the system into key low pressure zones of the trailer. The end result, a significant reduction in aero drag without sacrificing the cargo volume or ease of access to the trailer doors. The system can also shut off at lower speeds to reduce energy consumption or at higher speeds as way to intentionally increase drag to help slow down the truck.

Regenerative braking- although it is not the ideal application to use on vehicles that drive long distances at fairly constant speeds. The generator can provide some braking and energy recovery to reduce stress on the brakes through mountainous regions or to help reduce energy use in stop and go traffic situations.
