The 2007 Nissan 350Z, scheduled to go on sale in January 2007, offers a number of enhancements for the new model year, including the next generation of its award-winning VQ-series 3.5-liter V6 engine with 306 horsepower and 268 lb-ft of torque. Also added are three new exterior colors – Carbon Silver, San Marino Blue and Solar Orange. A Bluetooth® Hands-Free Phone System has been added to the Touring and Grand Touring Coupe models, and a gray Roadster soft top replaces the previous blue top (in addition to the available black soft top).
For 2007, the 350Z is available in Coupe and Roadster body styles and in an array of models – four for the Coupe and three for the Roadster. Each provides sports car lovers high performance excitement and dynamic driving experience, with a style all its own.
The 350Z Coupe and 350Z Roadster share a proud performance heritage, including a state-of-the-art platform, engine, suspension and braking systems. The heart and soul of the Nissan Z®, since the original 1970 model, is its engine. Every 350Z offers a new VQ35HR 3.5-liter V6 engine, which for 2007 produces 306 horsepower @ 6,800 RPM and 268 lb-ft of torque @ 4,800 RPM, with more than 90% of torque available between 2,000 and 7,000 RPM.
The fourth-generation VQ-series V6, which has been named one of the ‘Ten Best Engines’ by Ward’s Auto World magazine for 14 consecutive years, has been significantly revised for use in the 2007 350Z, with approximately 80% of major parts (except bolts, O-rings and clips) redesigned.
The block features ladder frame construction for greater rigidity, crank journal and pin diameters have been increased and the block height has been increased by 8.4 millimeters to reduce piston side force. Also, the engine center has been lowered 15 millimeters. Other engine enhancements include variable exhaust cam timing (eCVTCS), a higher rev limit (increased to 7,500 rpm) and higher compression ratio (from 10.3:1 to 10.6:1), asymmetric piston skirts, twin knock sensors, improved coolant flow and new Iridium-tipped spark plugs.
A new symmetric twin ram air intake system helps reduce airflow resistance and increases horsepower, by up to three horsepower, as more air enters the intake at speed. Along with a powerful engine, the Z® produces a powerful sports car sound to match – one without the low frequency booming or rumbling or high-pitched mechanical sounds that can grow tiresome on long trips.
‘With the new VQ35HR engine, we’re able to offer the true sports car enthusiast more power, a better sound, and an improved overall driving experience,’ said Bill Bosley, vice president and general manager, Nissan Division. ‘At the same time, we’ve kept the beautiful balance of the Z® in terms of unique style, comfort and value.’
Both a 6-speed close-ratio manual and a 5-speed automatic transmission are available. The manual transmission features close-ratio gearing from 1st to 5th speed ranges for high-performance driving and an overdrive 6th speed for long-legged highway fuel economy and reduced engine noise. The advanced automatic transmission design includes Downshift Rev Matching (DRM), which provides smooth downshifting by automatically blipping the throttle.
The Z®’s FM (Front Mid-Ship) platform positions the engine behind the front axle, providing an optimized front-to-rear weight balance of 53/47. The FM platform, derived from racing technology, also places a strong emphasis on aerodynamics, especially on the control of airflow under the body.
The Z®’s standard rack-and-pinion steering system features a vehicle speed-sensitive power assist, which provides comfortable steering effort at both low and high speeds. The system’s two orifice sets (compared with one set for traditional power steering systems) work together to generate the appropriate level of steering effort for nearly every driving condition. The orifice sets are controlled by a solenoid valve and electrical control units.
The Z®’s suspension is a 4-wheel independent multilink design with extensive use of lightweight aluminum components and standard front and rear stabilizer bars.
The 2007 350Z offers a power-assisted 4-wheel disc Anti-lock Braking System (ABS) with Electronic Brake force Distribution (EBD) and Brake Assist. (BA)
Brembo brakes, featuring four-piston front caliper pistons and two-piston rear calipers, larger brake pads and larger rotors are standard on the Coupe and Roadster Grand Touring models for even more superb stopping power.
Traction Control System (TCS) and available Vehicle Dynamic Control (VDC) work in conjunction with the Z’s braking system. TCS uses the ABS wheel speed sensors to detect if the rear wheels are accelerating faster than the front wheels. If so, torque is reduced to the drive wheels by altering the fuel injector pulse and controlling the Electronic Throttle Control motor. Working hand-in-hand with the ABS and the TCS, VDC can reduce engine torque or apply individual brakes as necessary to help stabilize the car under severe cornering situations or adverse weather conditions.
The Z® features standard 18-inch cast aluminum-alloy wheels, mounted with 225/45WR18 (front), 245/45WR18 (rear) Bridgestone® Potenza RE050A tires.
RAYS super lightweight 5-spoke forged-alloy wheels, 18×9-inch front and 19×10-inch rear, are standard on 350Z Grand Touring models. The wheels are mounted with 245/40WR18 (front), 265/35WR19 (rear) Bridgestone Potenza RE050A tires. All 2007 Z®s also feature a standard Tire Pressure Monitor System (TPMS).
