The 2015 Audi TT Offroad Concept has been officially unveiled ahead of its premiere at the Beijing Motor Show 2014 tomorrow. The TT Offroad Concept is one of a number of SUV concepts hitting the show floor this week. The Audi made its debut at the pre-show VAG conference as tradition dictates!
The Audi TT Offroad Concept forms part of the Audi e-Tron range. As such it features a plug-in hybrid drive unit with two electric motors and a total system output 408 hp and 650 Nm of torque. The Concept is intended to preview a potential niche Audi engineers might choose to exploit with the new TT platform. Audi are keen to publicise the remarkable efficiency of the power train which runs on 1.9 liters of fuel per 100 kilometers (123.8 US mpg).
The combustion engine is a 2.0 TFSI four cylinder engine producing 292 hp and 380 Nm of torque. The power is achieved through the use of a large turbocharger. Interestingly, the exhaust manifold is integrated into the cylinder head. A seperating clutch links the transverse 2.0 TFSI to a 40 kW 220 Nm electric motor.
To transfer the power, Audi fits a six-speed e-S tronic, dual-clutch transmissions. Torque from the front electronic motor is sent to the front wheels and mounted to the rear axle is a second electric motor independent of the front drive unit producing 85 kW and 270 Nm of torque. The TT Offroad Concept gets a liquid-cooled, lithium-ion battery comprising eight modules. These can be topped up using an Audi wall box. The show car uses Audi Wireless charging technology with contactless inductive inductive charging which begins when the TT drives onto a plate.
The show car accelerates from 0 to 100 km/h in 5.2 seconds and reaches an electronically governed top speed of 250 km/h (155.3 mph) without any trouble. It is able to travel 50 kilometres solely on electric power and with zero emissions. Audi states the total range as being up to 880 kilometers (546.8 miles).
The Offroad Concept gets an Audi drive select management system which offers three driving modes. EV mode gives priority to electric driving. In this case, the front drive unit is inactive, and the electric motor at the rear axle operates to a maximum of 130 km/h (80.8 mph). In Hybrid mode, all three drive modes work together in various ways. The front electric motor assumes the role of a generator, extending the rear motors range.
Full system output is available in Sport mode. This essentially makes the Audi TT offroad concept an e-tron quattro. When the driver takes his or her foot off the accelerator, free-wheeling or “coasting” is activated. Recuperation happens at low speeds and when braking. The driver can use the “Hold” and “Charge” functions in the MMI system to influence the battery’s charge state. Weight balance is 54:46 between the front and rear axles.
The concept gets 21 inch wheels with 255/40-series tires. The McPherson front suspension is crafted from aluminium, whilst the rear gets a four-link setup. The TT Offroad Concept previews two production ready technologies; intersection assistant and online traffic light information technology. Intersection assistant aims to help to avoid side impact collisions by using radar sensors and a wide-angle video camera scan zones at the front and sides of the car. If the system detects a vehicle approaching from the side and assesses it to be critical, graduated warnings are displayed on the Audi virtual cockpit.
Online traffic light information is a technology that connects the Audi TT Offroad Concept via a mobile phone network to the central traffic computer, which controls the traffic light systems in the city. Based on the information from this system, the Audi virtual cockpit shows the driver what speed to drive in order to reach the next traffic light while it is green. The cockpit displays the time remaining when waiting for the light to turn green. Soon we’ll see Audi drivers racing from light to light!
The Audi TT Offroad Concept is based on the modular transverse matrix (MQB). It uses an ASF (Audi Space Frame) constructed from a hybrid of steel and aluminum components. Its dimensions are similar to the Audi Q3 but it is 8 centimeters (3.2 in) lower, making it sportier in character. The exterior colour is Sonora Yellow.
The 2015 Audi TT Offroad Concept offers enough interior space for four adults. It gets individual sport seats with integrated head restraints in true Audi fashion. The top of the instrument panel is apparently designed as a wing and the round air vents are a particularly important part of the interior design, incorporating the air conditioning unit controls!
The “Audi virtual cockpit” includes a 12.3-inch TFT display with high-quality 3D graphics. It is dominated by the speedometer and the power meter for the plug-in hybrid drive. In Infotainment mode, elements such as the navigation map or online traffic information displays take center stage. Aside from the normal cubby holes, the TT Offroad Concept also features the Audi phone box which connects the driver’s mobile phone to the on-board electronics and also charges it inductively, when necessary.
The show car’s ventilation system also includes an ioniser which significantly improves the quality of the air in the cabin. Three Audi Smart Displays also feature as a mobile infotainment system for use inside and outside of the car. From DVD or TV streaming to controlling the radio or navigation planning, the user now has access to all of the functions of the Android operating system.
