Update - An earlier version of this article stated the new 911 GT3 had a torque figure of 458Nm, along with top speeds of 317km/h for PDK models and 318km/h for manual versions. This is not the case. See article for details
The new 2018 Porsche 911 GT3 has been detailed for this week's Geneva motor show, ahead of its global launch later this year.
Headlining the track-focused model is a high-revving naturally-aspirated 4.0-litre flat six engine, producing 368kW of power and 460Nm of torque - 5kW up on the outgoing GT3 RS. This engine is based on the unit used in all 911 race cars, including the 911 GT3 Cup car and the 911 RSR.
Offered with a standard seven-speed PDK dual-clutch transmission or - as reported in recent weeks - a six-speed manual, the new 911 GT3 is capable of sprinting from 0-100km/h in 3.4 seconds (3.9 seconds manual) on its way to a top speed of 318km/h (320km/h manual).
The new 911 GT3 comes with rear axle steering as standard, which the company says offers "superlative handling characteristics" in conjunction with the chassis tune.
Depending on the vehicle's speed, the rear wheels will steer with or against the front wheels, helping to improve the GT3's agility and stability. Adding to this are dynamic engine mounts and a rear locking differential.
A carbon-fibre rear wing reinforces the track-focused persona visually while also improving downforce, while the front fascia, front spoiler and rear diffuser also contribute to overall aerodynamic efficiency.
Inside, the GT3 features a GT Sport steering wheel from the 918 Spyder hypercar, which measures 14.1 inches (35.8cm) in diameter, while the Sports Seats Plus front pews feature enhanced bolstering for more lateral support and electric adjustment for the seat back and seat height.
Porsche will also offer the 911 GT3 with 18-way power-adjustable Adaptive Sports Seats Plus which also includes a power-adjustable steering column, along with full bucket seats with electric height adjustment and a fixed carbon-fibre backrest.
Like all GT variants before it, the rear seats have been removed to save weight.
The GT3 will also come standard with the Porsche Communication Management (PCM) infotainment system as standard with satellite navigation and live traffic updates, along with the Connect Plus Module incorporating Apple CarPlay and the Porsche Track Precision App.
With the smartphone app - included as standard - drivers can display, record and analyse driving data on their phones.
The 911 GT3 is available to order now, with first Australian deliveries expected in the fourth quarter of 2017. It will be priced from $327,100 plus on-road costs.
