It’s interesting to see how ordinary motorists and amateur/semi-pro race drivers are so fascinated (bordering on obsessed?) with obtaining F1-like data and telemetry for their driving activities.
So much so, that there are any number of quite good (and improving) smartphone apps for the major platforms that aim to provide the motorsports telemetry experience to a wide audience. Some are free, some are quite expensive, but all have a large following. Some are better implemented than others, but there’s a growing trend for this type of application to come with back-end server support for more comprehensive playback and analysis. These server systems are (so far) by no means as professional or as comprehensive as something like the Magneti Marelli’s top-end WINTAX or ATLAS products, but much more accomplished than you would ever be able to get on your smartphone.
Stuttgart. GT sports cars from Porsche are a good ticket to the world of motorsport. Four out of five of all Porsche GTs ever built have been driven on the track. One in three enthusiastic drivers take to the track in the first year to test the sporting limits of their vehicle and their own abilities. Porsche has developed the Track Precision app especially for such drivers.
The Porsche Track Precision app is part of a special Sport Chrono Package, which is only available as an exclusive option for the Porsche GT sports cars Cayman GT4, 911 GT3 and 911 GT3 RS. It also includes the pre-fitting for connecting a lap trigger, which is available as an option from Porsche Tequipment. This lap trigger allows lap times to be measured even more precisely than using the GPS signal. You can download the free smartphone app for Android or iPhone from iTunes or Google Play. It allows the driver to perform a detailed and objective analysis of their lap times and driving style using synchronised data and video recordings. To do so, it utilises precise vehicle data from an auxiliary control unit in the vehicle as well as the smartphone’s high-resolution camera and GPS signals.
The Porsche Track Precision app offers a unique range of functions, both while driving as well as for subsequent analysis. Before setting off, the driver simply has to select the desired track. This can be done either before or during the approach to the track. There are already about 60 international racetracks available in digitised form so far. Additional tracks can be conveniently added in a map editor beforehand or can be created when you drive the first lap in the car. To ensure high video quality, the driver should then affix the smartphone in a secure mount on the windscreen. As soon as he passes the start line, the system automatically begins to record using the GPS data. The data can be saved with the tap of a finger after passing the finishing line when the car leaves the track. Continue reading Like in motorsport: recording and analysis of driving data on tracks→
BENTLEY REVEALS CONTINENTAL GT3 DETAILS AT GLOBAL DEBUT
Continental GT3 unveiled at the Goodwood Festival of Speed
600 bhp 4.0-litre twin-turbo V8 for 1300 kg racer
GT3 to drive the Goodwood hill-climb twice a day
Bentley debuts its new Continental GT3 race car at the 2013 Goodwood Festival of Speed today, unveiling a racing machine set to explore the extreme potential of Bentley’s iconic Grand Tourer, the Continental GT. Member of the Board for Engineering, Rolf Frech, comments: “The Continental GT3 exploits the incredible performance beneath the skin of every Continental GT. We’ve removed over 1000 kilograms of weight, reconfigured our 4.0-litre V8 to produce 600 bhp in race specification, and developed a comprehensive aerodynamic package to ensure that we perform competitively. We are now looking forward to getting the car on the track and proving its potential.”
The Continental GT3 is powered by a race-prepared and dry-sump version of Bentley’s powerful but efficient 4.0-litre twin-turbo V8, with many components carried over from the road-going engine. Developing up to 600 bhp in unrestricted race configuration via a motorsport engine management system, the V8 provides the GT3 with highly competitive power in a compact and lightweight package that’s perfect for racing. Power is transmitted to the rear wheels via a carbon fibre propshaft to an Xtrac six-speed sequential gearbox with a limited slip differential, mounted as a transaxle for optimised weight distribution. Gear actuations are completed via a pneumatic shift system, controlled by paddles mounted to the steering wheel.
A double wishbone suspension configuration front and rear, fitted with four-way adjustable racing dampers, replaces the standard road-car air springs. The steering system features hydraulic power-assistance, while braking is via ventilated iron discs combined with six-piston calipers on the front and four-piston calipers on the rear.
The exterior of the car features a comprehensive aerodynamic package, to maximise downforce with optimised drag. A top-mounted carbon fibre rear wing provides rear downforce and stability, while a carbon fibre splitter balances the aerodynamic forces at the front of the car. Revisions have been made to the bonnet, bumpers, fenders and sills in order to optimise the car’s drag coefficient and to assist with engine cooling.
The sportiest 911 will have its world premiere at the Geneva International Motor Show: the new Porsche 911 GT3. In the 50th anniversary year of the 911, Porsche is now set to open a new chapter in race track performance sports cars. The fifth generation of the 911 GT3, a complete new development, will take the pole position among the thoroughbred Porsche sports cars with naturally aspirated engines.
Boxer engine and transmission, as well as body and chassis are completely new and constitute a further development of the 911 GT3 concept with an impressive performance leap. Power: 475 hp. Power to weight ratio: 3.0 kg/hp. Acceleration from zero to 100 km/h: in 3.5 seconds. Top speed: 315 km/h. Lap time Nürburgring Nordschleife: under 7:30 minutes. As a technical highlight, it features the first active rear wheel steering in a production Porsche. As well as the optional full LED headlights. The new 911 GT3 keeps all the successful properties of a sports car suitable for racing, with even more driving dynamics, more sophisticated practicality – and a highly emotional fun factor. The powertrain of the new 911 GT3 is composed of a 3.8-liter boxer engine yielding 475 hp (350 kW) at 8.250 rpm, a Porsche dual-clutch transmission (PDK) and a high-traction rear-wheel drive.
On the Sebring International Raceway in Florida/USA the GTE race car from Weissach completed another successful test on Thursday. The successor to the Porsche 911 GT3 RSR will be run exclusively by the Porsche AG Team Manthey works squad at the 24 Hours of Le Mans and in the World Endurance Championship (WEC). The vehicle celebrates its race debut on April 14 at the WEC season-opener in Silverstone.
At the 2002 Paris Motor Show, the unveiling of the Continental GT concept took the world by storm and opened an exciting new chapter in Bentley’s history. Now, ten years on, Bentley is revealing the Continental-based GT3 race car currently being developed by a dedicated motorsport team at the company’s factory in Crewe.
Signalling Bentley’s return to the racetrack for the first time since its historic sixth Le Mans victory in 2003, Continental GT3 remains faithful to the company’s founding motorsport philosophy of developing racing cars from their road-going counterparts.
Dr Wolfgang Schreiber, Bentley’s Chairman and Chief Executive, comments: “The clear message from our customers is that Bentley belongs on the racetrack, and the Continental GT3 is the realisation of a dream we’ve had ever since the launch of the Continental GT. The new GT Speed is the perfect car for us to develop into a racer, and our work so far has shown huge potential. The Continental GT3 is set to show the world what the Continental GT is capable of in its most extreme form, and establishes a solid foundation for Bentley’s long-term motorsport plans.” Continue reading Bentley’s Continental GT3 – BENTLEY RETURNS TO MOTORSPORT WITH RACING GT→
