The Porsche 918 Spyder blows minds at the 2013 Goodwood Festival of Speed

The 2013 Goodwood Festival of Speed, an annual event to showcase automobiles new and old on an uphill race course, got a surprise from Porsche. An 887 horsepower hybrid known as the Porsche 918 Spyder tore up the hill to the admiring cheers of the crowd. The Porsche 918 promises to be one of the most exciting and unique Porsches to date.

The Porsche 918 Spyder has a vast array of settings to maximize the full potential of its technology:

“From comfortable to race-ready: five modes for three motors
The core of the 918 Spyder concept is its distribution of propulsive power among the three power units, and their co-operation is controlled by an intelligent management system. To best exploit these different approaches, Porsche engineers defined five operating modes that can be activated via a ‘map switch’ on the steering wheel, just like a race car. On the basis of this pre-selection, the 918 Spyder applies the most suitable operating and boost strategy without driver intervention, thus allowing the driver to concentrate fully on the road.

Quiet and elegant: ‘E-Power’
When the vehicle is started up, ‘E-Power’ is the default operating mode as long as the battery is sufficiently charged. In ideal conditions, the 918 Spyder can cover over 18 miles (30 km) on purely electric power. Even in pure electric mode, the 918 Spyder accelerates from 0 – 62 mph in less than seven seconds and can reach speeds of up to 93 mph. In this mode, the combustion engine is only used when needed. If the battery’s charge state drops below a set minimum value, the vehicle automatically switches to hybrid mode.

Efficient and comfortable: ‘Hybrid’
In ‘Hybrid’ mode, the electric motors and combustion engine work alternately with a focus on maximum efficiency and minimum fuel consumption. The use of individual drive components is modified as a function of the current driving situation and the desired performance. The Hybrid mode is typically used for a fuel economy-oriented driving style.

Sporty and dynamic: ‘Sport Hybrid’
In more dynamic situations, the 918 Spyder selects the “Sport Hybrid” mode for its power sources. The combustion engine now operates continuously and provides the main propulsive force. In addition, the electric motors provide support in the form of electric boosting or when the operating point of the combustion engine can be optimised for greater efficiency. The focus of this mode is on performance and a sporty driving style at top speed.

For fast laps: ‘Race Hybrid’
‘Race Hybrid’ is the mode for maximum performance and an especially sporty driving style. The combustion engine is chiefly used under high load, and charges the battery when the driver is not utilising its maximum output. Again, the electric motors provide additional support in the form of boosting. Furthermore, the gear-shifting programme of the PDK is set up for even sportier driving. The electric motors are used up to the maximum power output limit to deliver the best possible performance for the race track. In this mode, the battery charge state is not kept constant, but instead fluctuates over the entire charge range. In contrast to ‘Sport Hybrid’ mode, the electric motors run at their maximum power output limit for a short time for better boosting. This increased output is balanced by the combustion engine charging the battery more intensively. Electric power is thus available even with several very fast laps.

For pole position: ‘Hot Lap’
The ‘Hot Lap’ button in the middle of the map switch releases the final reserves of the 918 Spyder and can only be activated in ‘Race Hybrid’ mode. Similar to a qualification mode, this pushes the traction battery to its maximum power output limits for a few fast laps. This mode uses all of the available energy in the battery.

Main propulsion: the race car’s eight cylinder engine
The main source of propulsion is the 4.6-litre, eight cylinder engine that produces 612 hp of power. The engine is derived directly from the power unit of the successful RS Spyder, which explains why it can deliver engine speeds of up to 9,150 rpm. Like the race engine of the RS Spyder, the 918 Spyder power unit features dry-sump lubrication with a separate oil tank and oil extraction. To save weight, components such as the oil tank, the air filter box integrated into the subframe and the air induction are made of carbon fibre reinforced polymer. Further extensive lightweight design measures have resulted in such features as titanium connecting rods, thin-wall low-pressure casting on the crank case and the cylinder heads, a high-strength lightweight steel crankshaft with 180 degrees crankpin offset and the extremely thin-walled alloy steel/nickel exhaust system.” – – Porsche Media

I am overwhelmed at the potential of the Porsche 918. Not only is it a technological juggernaut, it represents fresh thinking and a willingness to build something courageous, like back in the days of the Porsche 959. Fortunately, the Porsche 918 is drop-dead gorgeous, whereas the 959 wasn’t.
