Volkswagen presenting e-up! and e-Golf EVs at Frankfurt

|e-up! and e-Golf.|
In a dual world premiere, Volkswagen will present two EVs at the International Motor Show (IAA) in Frankfurt: the e-up! (earlier post) and e-Golf (earlier post). The e-up! is highly efficient, with energy consumption of 11.7 kWh of electricity per 100 km (117 Wh/km) on the European cycle. (As a comparison, although not exact because of drive cycle differences, the Fiat 500e has an EPA-rated energy consumption of 18 kWh/100 km, or 180 Wh/km; the smart fortwo electric drive consumes 20 kWh/100 km, or 200 Wh/km.)
The e-Golf, positioned two classes higher than the e-up!, has an energy consumption rating of 12.7 kWh/100 km (127 Wh/km). Given an electricity price of €0.258 per kWh ($0.35/kWh) in Germany (as of 31 July 2013), driving 100 km there with the e-up! costs €3.02 ($4.04), and with the e-Golf it is around €3.30 ($4.42).
Volkswagen developed the e-motors, gearboxes and lithium-ion batteries of the e-up! and e-Golf in-house, and they are manufactured in large Volkswagen component plants in Germany.
The e-Golf is driven by a 85 kW / 114 hp electric motor, with maximum torque of 270 N·m (199 lb-ft). The e-Golf reaches 100 km/h in 10.4 seconds. On a motorway, the speed of the five-seat front-wheel drive car is electronically limited to 140 km/h (87 mph).
The electric motor in the four-seat e-up! produces 60 kW / 80 hp, with 210 N·m (155 lb-ft) of torque. Acceleration from 0 to 100 km/h takes 12.4 seconds; top speed is 130 km/h (81 mph).
The e-up! can drive 160 km (99 miles) on one battery charge (18.7 kWh), while the e-Golf with its larger battery (24.2 kWh) has a range of 190 km (118 miles). In both models, two very efficient driving modes (“Eco”, “Eco+”) and four regenerative braking modes (“D1”, “D2”, “D3” and “B”) help to extend maximum ranges. In Germany, studies by the Federal Ministry for Transport, Building and Urban Development found that around 80% of all car drivers in Germany drive fewer than 50 km (31 miles) daily.
Powertrain and fuel strategy. Over the past decade, Volkswagen has sketched out a schedule for the future in its powertrain and fuel strategy, which included starting points for electric vehicles such as the e-up! and e-Golf. (Earlier post.) This strategy sets up a timeline with realistic time windows for the introduction of alternative drive systems such as the hybrid, electric and hydrogen-based systems.
In this scenario, the all-electric drive system—as demonstrated by the new e-up! and e-Golf—represents what Volkswagen calls “an indispensable and sensible supplemental drive system”. That, the company says, is because electric cars can utilize renewable energy sources and enable zero-emissions mobility in metropolitan areas. Nonetheless, well into the future Volkswagen will continue to promote an intelligent mix of the most efficient drive systems.
The target group for electric cars is growing, Volkswagen adds, because a paradigm shift has begun. Sustainable mobility is having an increasing impact on people’s actions.
