UPDATE: MORE VIDEO – Porsche 935 K3 – Apple’s iPorsche – Tribute to Steve Jobs

Porsche 935 K3 – Apple

This is  the Apple Computer that car raced at the 1980 Le Mans 24hrs by Allan Moffat for Dick Barbour Racing. Driven by Bobby Rahal, Allan Moffet & Bob Garretson.

Unfortunately they retired after 11hrs with a melted piston. Later that year Rahal and Garretson, along with veteran Brian Redman won the Daytona 24 Hours. Allan Moffat later drove a Mazda RX 7 at Le Mans and finished 14th in 1982.

Before Bobby Rahal raced in the CART series and started Rahal Letterman Lanigan Racing (the team which builds and races the ALMS 90 and 92 BMW M3s), he drove a Porsche 935 sponsored by Apple Computers.


The Porsche 935 K3 was third in a line of 935 variants developed by Kremer Racing, the Kremer 3 (K3) had a twin-turbocharged, 3.2 litre flat six motor producing upwards of 740 to 800bhp.

But power alone would not be enough to battle the factory built 935’s so Kremer Racing focused on shedding weight. They replaced the factory fitted air-to-water intercooler with an air-to-air intercooler, replaced body panels with light weight composites, and made over 100 other upgrades.

All these changes are thought to have only given the K3 935 a 1% performance increase over their factory built counterparts but thats all that was needed. The 935 finally had its worthy adversary.

The history of the Porsche 935 K3 version was a hit. Klaus Ludwig won in 1979 almost all the races leading DRM championship and the 24 hour race at Le Mans. That the Kremer Brothers great rewards: In 1980 there were as many as 10 K3’s to the start of the famous 24-hour race. This reason partially in Group 5 and IMSA GTX partly in the class. This car of Dick Barbour fell after 11 hours with a broken piston, his teammate won the class.


The K3 version of the Porsche 935 was a fantastic car. After Ludwig DRM and won the Le Mans in 1979, the Kremer brothers sold lots of K3’s. In 1980 no less then 10 competed at Le Mans. This one retired with a broken piston after 11 hours.

LATEST UPDATE : In regards to the  Porsche Apple 935 , I heard a COPY of the Apple 935 is currently running in Europe.

 Apparently the owner does not tell people the car is a copy. It is basically a tube frame car with a real 935 motor but that is it. And not sure , but appears the copy of Apple 935 is not running in Europe, something happened to it..

Here is Roger Bolinger’ Mighty 700hp Pontiac TRANS AM chasing the Apple 935 copy around the track. Stay with the video…!

Porsche New top model with all-wheel drive and 408 hp (300 kW) Porsche just added a number: 4.

911 Carrera 4 GTS Carrera 4 GTS available as Coupé and Cabriolet with top-of-the-range Carrera engine

The 911 Carrera GTS made a clear statement as the most sporty 911 Carrera of all times.

Porsche just added a number: 4.

Discover the new all-wheel drive 911 Carrera 4 GTS on http://www.porsche.com/microsite/carrera4-gts/germany.aspx

Stuttgart. Dr. Ing. h.c. F. Porsche AG, Stuttgart, is widening the top end of its Carrera model line and pairing up each of the two 911 Carrera GTS with an all-wheel drive twin. That means that the 911 Carrera 4 GTS Coupé and Cabriolet will combine the 408 hp (300 kW) top of the range engine of the Carrera GTS family with the intelligent, all-wheel drive Porsche Traction Management (PTM). Driving dynamics are not the only source of attraction. Economics are as well.

Thanks to Porsche Intelligent Performance the new all-wheel 911s consume no more than the equivalent Carrera 4S version, the Coupé remains at 11.0 l/100 km (25.7 mpg imp.) and the Cabriolet at 11.2 l/100 km (25.2 mpg imp.) respectively based on the New European Driving Cycle (NEDC). Moreover both of them boast an even more comprehensive standard equipment package compared with the Carrera 4S models.

The 911 Carrera 4 GTS power unit has its origins in the 3.8-litre, six-cylinder
Carrera S engine.

A wholesale revamping of the intake duct added 23 hp (17 kW), taking the power output to 408 hp (300 kW) at 7,300 rpm. The special aspiration system not only improves peak power output but flexibility and power development as well thanks to a more generous torque curve in the lower and middle engine speed range. 320 Newton metres kick in from as low as 1,500 rpm; the six-cylinder engine delivers its rated torque of 420 Nm in the broad engine speed range from 4,200 rpm and 5,600 rpm.

The sports exhaust system fitted as standard ensures a distinctly sporty sound. It invests the new Carrera 4 GTS with an unmistakable acoustic signature and the rear view of its tail pipe with its unique black surface design lends it a unique character.

At full power the Carrera 4 GTS Coupé sprints to 100 km/h (62 mph) in 4.6 seconds, the Cabriolet in 4.8 seconds.

 

The Carrera 4 GTS is fitted as standard with a six-speed manual transmission but the Porsche-Doppelkupplungsgetriebe (PDK) seven-speed is available as an option if desired.

The PDK shaves an additional 0.2 seconds respectively off the acceleration times from 0 to 100 km/h (62 mph).

In the Carrera 4 GTS as well, PTM all-wheel drive stands for Porsche’s typical driving pleasure with even more driving stability, traction and agile handling.

What’s more, just how single-mindedly the Carrera 4 GTS is designed for driving dynamics is evident from the use of a standard limited-slip differential. This mechanical rear differential lock contributes to the driving dynamics of the electronically controlled all-wheel drive system.

The PTM achieves this by directing the optimal proportion of the engine torque to the front wheels via a multiple-plate clutch.

Visually, the new Carrera 4 GTS models with all-wheel drive differ in points of detail from earlier variants with rear-wheel drive: In addition to the type name on the doors and rear lid, the distinguishing characteristic of all models with all-wheel drive is the additional reflective stripe between the taillights. What the Carrera GTS models have in common is the 911’s wide body, otherwise reserved for the all-wheel version of the 911s, and the rear axle track width that goes with it.

In numerous other details as well the GTS models differ both visually and technically from the other Carrera models. For example, they run on 19 inch RS Spyder wheels in black with central locking and gloss-lathed rim flanges fitted with 305/30 ZR 19 tyres on the rear axle.

Additional visual features include the Sport-Design front apron with black painted spoiler lip and special side skirts, also in black. Driver and passenger are accommodated on sports seats.

Typical of the GTS, the emphatically sporty black Alcantara covering on centre panels, steering wheel rim, gearshift and handbrake lever, door handles and door storage box lid and extension are offered as standard in addition to a range of leather upholstery options.

The 911 Carrera 4 GTS Coupé, including country-specific equipment and VAT at 19 per cent, is offered in Germany at a price of 111,956 euro, the Cabriolet costs 122,071 euro. Both models will be on sale in Germany from July 2011.
