The Electric Car - Porsche readying electric Taycan for 2019 reveal




Taycan the four-door has entered the second phase of prototype production, as Porsche prepares for its first electric model.

The countdown to the launch of the electric-powered Porsche Taycan has begun in earnest with officials revealing the new four-door saloon has now entered the second phase of prototype production at the company’s Zuffenhausen headquarters on the outskirts of Stuttgart in Germany.

The first in an extended line-up of electric-powered models being developed in a program budgeted to cost up to £5.3 billion through to the end of 2022, the Taycan marks a radical departure from Porsche’s traditional line-up, bringing full-time zero local emission compatibility together with the promise of what the new car’s lead engineer, Stefan WECKBACH, describes as a “typical Porsche driving experience”.

When it goes on sale in the UK following a planned public premiere at the Frankfurt motor show in September 2019, it will be positioned between the £55,965 Cayenne and £67,898 Panamera in a move that will set the scene for the introduction of other new battery-powered Porsche models, including an electric-powered Mid-Engined sports car in the mould of the existing Boxster and Cayman and an SUV similar in size to the recently face lifted Macan.

Auto car can confirm the Taycan, previewed by the original Mission E concept, will be offered in two distinct variants with the standard saloon depicted here in prototype guise planned for right-hand-drive delivery in Britain in early 2020 and a more ruggedly styled high-riding estate-cum-crossover model previewed by the Mission E Cross Turismo concept revealed at the Geneva motor show earlier this year scheduled to see local showrooms in 2022.

Taycan rivals include Tesla Model S


Among the key rivals for the new Porsche is the Tesla Model S – a car used as an initial benchmark during the early phases of the Taycan’s development. However, Weckbach acknowledges the new four-door will also compete against a host of other upcoming electric car offerings, including sister company Audi’s E-tron GT as well as the recently spied Mercedes-Benz EQ S.

As evidenced by the latest prototypes fitted with production-based bodywork, the styling of the Taycan draws heavily on the well-received Mission E concept first shown at the 2015 Frankfurt motor show. Although every detail and body panel has been altered on the way to production, it remains faithful in appearance and overall visual character and detailing to the earlier concept, whose design is credited to Porsche’s former head of exterior design Mitja Borkert, now head of design at Volkswagen sister company Lamborghini.

Taking full advantage of the packaging advantages inherent in its drivetrain layout, the initial low-slung four-door saloon model combines the fundamental short-nosed proportions of traditional rear- and mid-engine Porsche models at the front together with the stretched proportions of more modern front-engine models towards the rear, providing the Taycan with clear design links to existing Porsche models, most notably the 911 and Panamera.

One major departure from the earlier Mission E is the adoption of sturdy B-pillars and four front-hinged doors in a measure aimed at increasing body rigidity. At the rear, the Taycan also receives a short notchback-style boot lid housing a full-width light band that provides access to one of two luggage compartments; the other is sited up front and is claimed to boast a near-to-100-litre capacity.

Dimensionally, the new Porsche is around 4850 mm in length and 1990 m in width, making it 199 mm shorter but 53 mm wider than the second-generation Panamera. By comparison, the Tesla Model S stretches to 4975 mm in length and 1965 mm in width.

More than one body style due for Taycan


The initial saloon and crossover are just two body styles created by Porsche designers for the Taycan. Others not yet revealed to the public include two-door coupél and cabriolet proposals, the likes of which insiders at the German car maker’s headquarters say could be added to the line-up at a later date when production capacity is freed up should demand warrant it.

The basis for the Taycan is the J-1 platform – a high-strength steel, aluminium and carbon fibre structure designed to house battery modules of varying sizes as low as possible within the confines of a long wheelbase. As well as being used by the new Porsche, it is also planned to underpin the upcoming Audi E-tron GT in a move aimed at increasing economies of scale.

Significantly, the new platform has been conceived exclusively as a dedicated electric vehicle architecture with Weckbach confirming it does not accept a combustion engine. It does, however, form the basis of a more versatile structure being developed in an engineering program between Porsche and Audi called the Premium Platform Electric (PPE).

The interior of the Taycan is described as providing a typical 911 style driving position up front with adequate rear seating on two individual seats in the rear. Prototype versions sighted by Auto car at Porsche’s Zuffenhausen factory reveal the otherwise entirely flat floor pan of the J-1 platform structure receives two sizeable foot wells in the rear to increase rear-seat accommodation.

Technology behind the Taycan


As hinted to by the Mission E, the Taycan is powered by an electric drive train with a permanent magnet synchronous motor housed within each axle in a layout that provides it with four-wheel drive capability.

Porsche chose synchronous motors against the asynchronous motors favored by Audi due to their ability to provide strong sustained performance at high energy density levels – characteristics it says are key to the new car’s development aims.

The electric motors are similar in design to the unit employed on the petrol-electric hybrid driveling used by the Le Mans-winning 919 Hybrid, with a solenoid coil featuring rectangular rather than round wiring.

This has enabled Porsche to package the copper wires within the solenoid coil more tightly together to make the electric motors smaller than they would be using more conventional round wires. A similar solenoid design is being considered by BMW for the motors to be used by the production version of its Vision iX3 concept car due out in 2020.
