Aston Martin Racing V12 Vantage GT3 Specs

Aston Martin Racing Confirms Specifications of new V12 Vantage GT3

Gaydon, 24 August 2011. Aston Martin confirms today the specification of the 2012 Vantage GT3 race car. As the natural successor to the enormously successful DBRS9, the new Vantage GT3 will offer customers the latest in race-car technology to ensure the Vantage GT3 has the credentials to compete with the most recent new product offerings from other manufacturers.

The Vantage GT3 features a modified version of Aston Martin's production 6.0 litre V12 engine found in the marque's highly acclaimed sports cars. The dry-sumped engine is expected to produce 600 bhp with 700 Nm of torque and its position has been optimised further to improve weight balance. A carbon fibre propshaft mates the engine to a Xtrac 6 speed sequential transmission with semi-automatic paddle shift gear change.

The Vantage GT3 benefits from Aston Martin's V/H architecture philosophy, the modular chassis uses aerospace bonding techniques to create a light and immensely stiff aluminium and composite structure which not only aids handling on Aston Martin's road cars but is also an ideal base for competitive race cars.

Most dramatic of all, are the new aerodynamics, contributing to a muscular and purposeful stance while maintaining the overall beauty of the V12 Vantage. The shorter wheel base and lower engine position over its predecessor will contribute to enhanced handling and performance. The new car will also provide enhanced driveability with the latest race-developed ABS and Traction Control systems which are fitted to the V12 Vantage GT3 as standard.

The Vantage GT3 will be eligible for numerous race series around the world including the FIA GT3 Championship, ADAC Masters, Nürburgring VLN, Blancpain Endurance Series, British GT, Belcar and Open GT among others.

Aston Martin remains the only manufacturer to offer a race car for every GT class firmly cementing it as a global forerunner in race car production. The new Vantage GT3 is being developed to replicate and indeed surpass the superb track record of the DBRS9.

Aston Martin has sold 24 DBRS9s and customer teams have accumulated many race podiums and victories over the past six years including 2009 Winner Teams Championship, and Winner Manufacturers Championship for Hexis Racing and as recently as a 2011 GT Open race win at Spa for Villois Racing.

Testing of the new car will commence in October, where the Vantage GT3 will undergo a comprehensive sign-off durability test including a 10,000 km test programme. Deliveries of the first cars will commence in early 2012. Prices start from £298,000.V12 Vantage GT3 Specification

Porsche 911 GT3 RS 4.0: Biggest 911 Engine Ever Offered

Limited-edition car is packed with motorsport technology

ATLANTA – April 28, 2011 --- The 911 GT3 RS, one of Porsche's most popular, coveted and successful track-inspired production cars, has been given a final, thrilling injection of thoroughbred motorsport technology resulting in the 2011 Porsche 911 GT3 RS 4.0. Limited to 600 vehicles worldwide, the 911 GT3 RS 4.0 brings together in a sports car the attributes that have made the Porsche 911 GT3 a consistent winner on the race track.

The motorsport-derived 4.0-liter engine, already the highest displacement 911 engine ever, also features the highest per-liter output -- 125 horsepower (hp) per liter -- from a naturally aspirated Porsche flat-six engine. The engine uses forged pistons, the connecting rods are fashioned from titanium, and the crankshaft has been lifted unchanged from the 911 GT3 RSR race car. It achieves its maximum power of 500 hp at 8,250 rpm. Maximum torque of 339 ft/lbs is reached at 5,750 rpm.

The 911 GT3 RS 4.0 offers truly impressive performance, lapping the famed Nürburgring-Nordschleife in 7 minutes and 27 seconds. Available exclusively with a six-speed manual transmission, the 911 GT3 RS 4.0 sprints from 0 to 60 mph in only 3.8 seconds, and with its gearing designed for the race circuit it reaches the 124 mph mark on the race track in under 12 seconds.

The 911 GT3 RS 4.0's outstanding driving dynamics come from numerous, meticulously coordinated details. In addition to using suspension components typically encountered in motor racing, weight reduction is also of supreme importance. Equipped as standard with lightweight components such as light but strong carbon fiber sport bucket seats, carbon fiber front fenders and luggage compartment lid, and weight-optimized carpets, the two-seater's ready-for-action weight is just 2,998 lbs with a full fuel tank. The 911 GT3 RS 4.0's power-to-weight ratio is 5.99 lbs/hp.

This limited edition 911 is painted Carrara White as standard and emphasizes its proximity to motor racing by its dynamic appearance. Signature characteristics are the wide track, the low vehicle position, the large rear wing with side plates, central twin tailpipe, and the aerodynamically optimized body. Air deflection vanes mounted on either side of the front bumper – called 'flics' or dive planes – make their first appearance on a production Porsche. They create increased downforce on the front axle, and together with the steeply inclined rear wing, provide aerodynamics on par with its performance capabilities. As a result, at the 193 mph top track speed, aerodynamic forces exert an additional 426 lbs of downforce, thus pushing the 911 GT3 RS 4.0 onto the road.

Vantage GT3

ASTON MARTIN RACING ANNOUNCES NEW VANTAGE GT3

Gaydon 13 April 2011. Aston Martin Racing announces today, the new Vantage GT3 race car based on the V12 Vantage road car, which will be ready for competition in 2012.

The Vantage GT3 will replace the DBRS9, launched in 2006 at Le Mans, and which has since seen 26 chassis built and raced to multiple victories in national and international series across the world most recently winning in the Australian GT at Mount Panorama in October last year and achieving a podium finish at Zolder last week. The new Vantage GT3 joins the Vantage GT2, GT4, DBR9 GT1 and the AMR-One LMP1 to create the largest and most comprehensive range of Aston Martin race cars to date.

Designed to FIA regulations, the Vantage GT3 will be built around the Vantage aluminium VH architecture with a lightweight dry-sumped 6.0 litre V12 engine, based on the V12 Vantage road car. The new car will have a race semi-automatic paddle shift Xtrac gearbox and the latest race-developed ABS and traction control systems, optimised for the Vantage GT3.

John Gaw, Aston Martin Racing Managing Director added: "The DBRS9 has been a very successful GT3 racing car and, despite being more than six years old, is still competitive today.

"However, the competition has moved on and we needed to create a new car that combines our six years' experience in this category with the latest race technology to continue Aston Martin's success in GT3 for many years to come."

Aston Martin Racing has set a target weight of 1250kg and target engine performance figures of more than 600bhp and 700Nm. The first car will be completed in July 2011 and will undertake an extensive test and development programme during the rest of the year. Ten customer cars will then be built ready for delivery for the start of the 2012 season.

2011 BMW Z4 GT3

Modified BMW Z4 GT3 Completes Successful Test Programme
Munich, 8th April 2011. The modified BMW Z4 GT3 has survived its baptism of fire: the GT customer sports car proved itself in a series of intensive tests in recent weeks. The goal of the latest modifications was primarily to improve aerodynamic efficiency in order to ensure the car's competitiveness in the many, hard-fought GT3 classes.

The BMW Z4 GT3, which was launched in March 2010, achieved its greatest success to date in January 2011. Claudia Hürtgen (DE), BMW works driver Augusto Farfus (BR), Tommy Milner (US) and Edward Sandström (SE) won the Dubai 24 Hours for Team Schubert. This was the first outright victory for the BMW Z4 GT3 at a marathon race of this scale, having already proven its potential with wins in its debut season in the FIA GT3 European Championship.

With its elongated bonnet, the driver's compartment towards the rear of the car, long wheel base and narrow wheel arches, the series version of the BMW Z4 boasts an unmistakable appearance. The two-seater provided BMW Motorsport engineers with a good basis for developing a competitive GT3 racing car.

A difference between the production and racing car can be found under the bonnet: while the production version of the BMW Z4 is driven by a six-cylinder engine, the GT3 car is powered by a 4.4-litre eight-cylinder engine.

BMW Motorsport engineers have also fine-tuned the aerodynamics of the BMW Z4 GT3 for the new season, improving the car's performance in this area. When it comes to electronics, the private teams can look forward to innovative BMW solutions: The modern ECU408 takes over the engine management, while the Power400 electronic control unit is responsible for controlling all the actuators. The power is transmitted through a six-speed, sequential gearbox. Gearshifts are now initiated using two paddles.

The steel body of the car comes from BMW Plant Regensburg. A safety cell made of extremely rigid, precision steel tubing is then welded into the body. The engine block of the V8 engine is produced in the BMW foundry in Landshut. BMW Plant Dingolfing contributes the rear axle differential, among other things. Front and rear wings, bonnet, roof, fenders and many other components are made of carbon fibre reinforced plastics (CFRP).
