The Porsche 918 Spyder is a car to be reckoned with. The racing car has a tough rival to contend with, the McLaren P1. Both will offer an interesting battle in the sales charts, being two of the fastest road cars ever.

We first saw the Porsche in 2010 at the Geneva Motor Show. It stole the show, being the highlight of the event. That concept at the time gave us an insight into the future, with hybrid technology playing a massive part in future sports cars.

One advantage that Porsche has is that it will be a lot cheaper than the McLaren, costing around £550,000. The P1 will command between the £700,000 and the £800,000 mark, being made available in showrooms from next year. There’s also one more rival well worth mentioning, the brand new Ferrari which will be the replacement to the spectacular and highly desired Enzo.

Both were recently tested at the same private race track, Observations clearly indicated that the Porsche 918 Spyder is the bigger of the two. They are both similar in the power of what they use, with McLaren developing a tremendous 850 BHP from its 3.8 litre twin turbo V8 engine. The car will also adopt a KERS hybrid system, making the vehicle more efficient.

The Porsche 918 Spyder is able to produce a total of 795 BHP thanks to its 4.6 litre V8 engine. The non turbo engine is mated to a PDK gearbox, suiting the vehicle perfectly. The car has two electric motors, being a plug in hybrid.

Both vehicles will be able to reach an outstanding 0-62 MPH speed of less than three seconds.

As you may have guessed, the Porsche 918 Spyder and the McLaren F1 will have a dominant carbon fibre chassis along with active aerodynamics, helping the car to be stronger, faster and more efficient. The rear wings are automatically adjusted too.

Each vehicle will made placed into showrooms on memorable dates to the company. The McLaren P1 will be released near to the company’s 50th anniversary. The production of the Porsche will start on September 18th which is also known as 9/18, a key date in Porsche’s American history. The Porsche 918 Spyder is expected to be released later on in 2013.
