Close-Up: Audi R8 E-Tron Powertrain [Video]
340 kW of power, 0 to 100 km/h inwards 3.9 seconds too a driving attain of upward to 450 km
Visually, the 4.40 meter (14.4 ft) long Audi R8 e-tron is recognizable past times its unique lighting solutions on the air inlets, front end apron too sideblades. Its outside skin, painted inwards Magnetic Blue, combines trunk parts made of aluminum too carbon fiber reinforced polymer (CFRP), such every bit the front end too parent lids. Thanks to aerodynamic modifications to its cooling air inlet, parent spoiler, diffuser, underbody too sideblades, the drag coefficient (Cd) of the R8 e-tron is simply 0.28. Its Audi Space Frame (ASF) is based on the multimaterial blueprint of the V10 version, which is extended past times a parent trunk module made of CFRP. Despite its depression weight, the corrugated bulkheads that conceal the luggage compartment tin give the sack absorb a lot of loose energy inwards a rear-end collision.
The T-shaped battery is structurally integrated inwards the middle tunnel too is mounted behind the occupant jail cellular telephone – this location offers a depression centre of gravity too an axle charge distribution of 40:60 (front/rear). The high-voltage battery is based on lithium-ion technology. The liquid-cooled lithium-ion battery consists of 52 modules. Compared to the starting fourth dimension e-tron applied scientific discipline platform, the loose energy capacity of the novel 595 kg (1311.8 lb) battery organisation was boosted from simply about 48.6 kWh to 90.3 kWh without requiring whatsoever bundle modifications.
Thanks to the high loose energy density, which was increased from 84 to 152 Wh/kg, the R8 e-tron tin give the sack endure driven upward to 450 km (279.6 mi) on simply ane battery accuse – previously it was 215 km (133.6 mi). In the Combined Charging System (CCS) for charging amongst DC or air-conditioning electricity, the battery tin give the sack endure fully charged inwards good nether ii hours. The driver tin give the sack command this procedure remotely past times smartphone, if the user has installed the relevant Audi connect app.
920 Nm (678.6 lb-ft) of torque
The ii electrical motors on the parent axle each output 170 kW too 460 Nm (339.3 lb-ft) of torque. The R8 e-tron, which weighs simply 1,841 kg (4058.7 lb) empty (without driver), sprints from 0 to 100 km/h (62.1 mph) inwards 3.9 seconds too tin give the sack accelerate to an electronically governed plough over speed of 250 km/h (155.3 mph) spell developing its unique e-sound. Targeted Torque Vectoring – a need-based distribution of motility mightiness betwixt the parent wheels – gives the automobile maximum stability too dynamism.
Intelligent loose energy administration too an electromechanical brake organisation at the parent axle ensure high rates of loose energy recuperation. The recess springs consist of drinking glass fiber reinforced polymer (GFRP), too the anti-roll bar is made of CFRP.
The R8 e-tron rides on aerodynamically optimized, high-gloss 19-inch aero wheels that were peculiarly developed for this car. At the front end axle, size 225/40R19 tires enable precise steering response. Size 275/40R19 tires transfer the torque of the electrical motors to the road. The tires were peculiarly developed for the requirements of an electrical supercar, too they combine sporty driving properties amongst efficient rolling resistance values. Extremely sporty 20-inch wheels of the production R8 are available via the Audi Genuine Accessories program.
In the finely crafted interior, the R8 e-tron offers illuminated door sill trims, folding bucket seats too a peculiarly configured Audi virtual cockpit. H5N1 oestrus catch removes waste materials oestrus from electrical components for thermal administration too for interior climate command – an of import efficiency module of the overall concept.
Audi too uses the latest evolution phase of the R8 e-tron every bit a high-tech laboratory – it too continues to play an of import purpose inwards developing electrical mobility of the future. The R8 e-tron volition endure produced inwards the small-scale production facility of quattro GmbH at the Audi Neckarsulm site inwards the Böllinger Höfe.
450 km (279.6 mi) attain on a fully charged battery
The novel battery cells are primarily responsible for the novel functioning too driving attain of the Audi R8 e-tron. Audi has systematically adapted its high-voltage battery organisation to the specific needs of electrical cars – the principal focus was on achieving an optimal ratio betwixt mightiness too energy. The results: The R8 e-tron has a significantly longer driving attain too fifty-fifty to a greater extent than mightiness than the previous model. In developing the high-voltage battery, the build amongst the 4 rings followed the regulation of maximum flexibility without losing sight of synergies inwards electrification. Its flexible jail cellular telephone module concept makes the Audi build well-equipped for all hereafter marketplace topographic point developments, spell the modular concept too guarantees Group-wide work across dissimilar automobile models.
The battery operates amongst 385 volts of nominal voltage, too its novel jail cellular telephone module concept achieves first-class performance. The battery’s loose energy density grew from 84 watt-hours per kilogram (Wh/kg) to 152 Wh/kg, too its nominal capacity from 48.6 kWh to 90.3 kWh. Its driving attain on a amount accuse has to a greater extent than than doubled – from 215 km (133.6 mi) to every bit much every bit 450 km (279.6 mi). These values build Audi the leader amidst the competition.
The battery organisation of the Audi R8 e-tron takes on the shape of a “T”. It measures 235 cm (92.5 in) long, 136 cm (53.5 in) broad too seventy cm (27.6 in) high, including the junction box on the cross-bar of the “T”. This junction box is responsible for monitoring, switching too transmitting an electrical electrical flow of over 1,200 amperes. The highly complex battery organisation consists of over 10,000 private parts.
The 7,488 cells are packed inwards 52 modules of 144 cells each. Each module weighs 7.8 kg (17.2 lb). They are arranged on ii too 5 levels (“floors”) inwards the tunnel battery too inwards the parent battery. Aluminum plates split the “floors” from ane some other spell creating the supporting construction for the battery.
Coolant circulates inwards a cooling organisation of aluminum shells. In a crash, high-strength flooring plates too acquit upon plates redirect the crash forces into the multimaterial ASF (Audi Space Frame) of the R8 e-tron inwards a defined way.
40:60: axle charge distribution
The 595 kg (1311.8 lb) battery organisation is joined to the ASF amongst bolts inwards the middle tunnel too behind the occupant cell, making it an integral business office of the vehicle structure. Its mounting topographic point results inwards a depression centre of gravity too an axle charge distribution of 40:60 (front/rear), which is ideal for a mid-engine sports car.
The Combo 2 charging interface of the Combined Charging System inwards the Audi R8 e-tron enables charging amongst air-conditioning or DC electricity. When charging amongst air-conditioning from an industrial electrical outlet amongst 7.2 kW of charging power, a amount accuse is reached inwards simply exactly about 12 hours. Charging amongst DC electricity shortens the fourth dimension – to simply 95 minutes at a charging mightiness of 50 kW. Audi is demonstrating charging equipment that tin give the sack accuse this battery organisation amongst upward to 150 kW of charging power. For the driver of the R8 e-tron, this way that a driving attain of simply about 150 km (93.2 mi) tin give the sack endure attained later simply xv minutes of charging time. The client tin give the sack care charging remotely every bit good – using a smartphone on which the client has installed the relevant Audi connect app.
