Nissan's iconic 36-year-old flagship sports car, the 350Z, has been released with new features including a more powerful engine and enhancements to its exterior and interior.

The Z is available in more than 95 countries and has sold around 1.6 million units worldwide since its initial release in 1969. The current fifth-generation Z (Z33 model) alone has sold a total of 160,000 units globally since its release in July 2002.

As part of the 2006 model year update, the 350Z is now available with a 221kW engine across the range. The 350Z's VQ35DE engine - the same engine that powered the 350Z anniversary model - has been boosted to 221 kW on six-speed manual models, up from 206 kW.

The 350Z's engine power was increased by improving induction efficiency with larger-diameter air ducts and retuning the valve timing and now generates 221kW of power @ 6400 rpm and 353 Nm of torque @ 4800 rpm.

All five-speed automatic variants come with a 206kW version of the VQ35DE engine which produces 363 Nm of torque at 4800 rpm.

Independent multi-link suspension front and rear with a front strut tower brace and an integrated rear strut tower brace combined with front and rear stabilizer bars guarantees sure-footed handling and dynamics.

Modifications to the suspension tuning and steering assistance have improved the ride, handling and feedback to create a more harmonious driving experience.

All Touring models now receive larger 320mm front brake discs (up from 296mm) and 308mm rear brake discs (up from 292mm) for improved thermal capacity (reduced brake fade) and improved feel.

While continuing the basic design cues popular among customers, the Z's exterior styling has been enhanced thanks to a redesigned front bumper and new Xenon headlamps, as well as the addition of high-brightness light-emitting diode (LED) rear combination lamps. The remodelled Z comes standard with newly styled 18-inch aluminium wheels on all grades.

The interior features greater use of authentic aluminium accents, soft-feel materials, steering wheel mounted radio controls, additional storage spaces, an optimised control switch layout and other refinements which enhance the Z's quality and ease of use.

Additional storage spaces include a cardholder, cargo net at the bottom of the front passenger's seat, illuminated beverage holders in both doors and larger door pocket openings for increased practicality for occupants.

All models feature composite carbon-fibre drive shaft, a traction control system, viscous limited-slip rear differential, electronic drive-by-wire throttle, dual outlet exhaust and the improved close-ratio six-speed manual transmission. A five-speed automatic transmission with manual mode and Downshift Rev Matching (DRM) is standard on Touring Roadster models and available as an option on the Touring Coupe.

The 2006 model year 350Z line-up consists of five variants - three Coupes and two Roadsters. The Touring Coupe is available with either the six-speed manual transmission for $62,990* or the five-speed automatic for $64,990*. The Track Coupe is now available with a manual transmission only for $67,990*.

The Roadster is available as either a manual-only Track for $73,990* or automatic-only Touring for the same price.

Standard features across the range include heated power adjustable leather sports seats, automatic climate control air-conditioning, Bose 240 watt sound system with seven speakers, power windows, door locks and mirrors and a three-bay gauge cluster for oil pressure, voltmeter and trip computer, dual front and side SRS airbags, curtain SRS airbags (Coupe only), cruise control and drilled aluminium pedals.

In addition to these features, the Track variants receive Brembo brakes, vehicle dynamic control (VDC) on both Coupe and Roadster variants. On Coupe Track models, there is also a front chin spoiler, under body diffusers and a rear spoiler for better aerodynamic performance.

According to Nissan's general manager sales & network development, Stephen Collins, the updates to the 350Z boost the performance and the overall appeal of the vehicle.

"The enhancements to the 2006 model year 350Z have brought substantial improvements to the driving experience," said Mr Collins.

"I think people will be pleasantly surprised when they drive the latest generation of our sports coupe and roadster."
