**** Durability Testing

1. Durable Convertible

To assure long-term durability, the convertible top at NCE undergoes extensive testing during development, being opened and closed more than 9500 times. Some of those cycles were performed in extreme conditions; temperatures ranging from minus -22° F to 170° F and humidity of up to 95 per cent. And an eight-minute water test consist of almost 7200 gallons of water are hurled at the car in a hurricane-like downpour at a pace of about 900 gallons per minute.
Every NCE Convertible undergoes a water test as it completes assembly.
Addressing another aspect of interior comfort, NCE’s Convertible three-layer top includes liner made of 3/4? foam sandwiched between a German twil weave cloth (topping made using polyester/acrylic blend surface cloth laminated with butyl rubber) outer fabric and an inner reinforcing cotton layer.
Engineers use a sophisticated human-ear mimicking device called the Aachen Head to measure noise levels. NCE’s Convertible achieves a better interior quietness acoustical rating than most other convertible in interior quietness.
For many of our clintes, NCE’s Convertible can be a collector car, something they might keep for generations. So we made sure the tops would retain their quality for a long time.

NCE is your resource to help validate designs and prove test components.
Test miles can be accumulated independently-operated test facilities, as well as on public roads surrounding NCE (The Center). Driving cycles can be duplicated or developed across the country for all terrains and climates.
NCE offers 24-hour-a-day, 7-day-a-week operation for fast, safe accumulation of test miles…1,200 miles a day…72,000 miles in less than two months.

2. Corrosion Testing

NCE’s extensive proving ground offers complete corrosion testing. NCE can etch, corrode, deteriorate, wear and decay just about any exposed materials in open or semi-open systems. Depending on the materials and applications, a passenger car vehicle can be tested to simulate accelerated corrosion results equivalent to one year in as few as 14 days.

3. NVH Testing

NCE’s extensive proving grounds can provide experienced professional test engineers. The engineers perform noise, vibration, harshness (NVH) test modes to meet your vehicle’s testing needs in a timely, accurate and well-planned and organized manner.

The NVH surfaces at NCE can provide manufacturers an opportunity to evaluate their products on many levels. Test your products to European and ISO noise testing requirements, ride quality, ground contact, handling, and suspension responsiveness.

4. Federal Motor Vehicle Safety Standard Testing (FMVSS)

When you need to crash it, crush it, or stop it, NCE’s proving ground offers you a full range of FMVSS and vehicle certification testing. NCE provides well-planned and organized test services in an accurate and timely manner to meet the compliance testing needs of manufacturers and government agencies.

NCE’s professional staff conducts FMVSS and certification tests. Services offered include:

  • FMVSS (static and dynamic)

    5. Facilities

    Facilities range from a Crash Test Laboratory to a 9,000-foot Skid Pad and Static Test Fixture Laboratory.

    Facilities range from the 7.5-mile High Speed Test Track, 50-acre Vehicle Dynamics Facility, numerous durability bump courses and a grueling 8-mile paved and gravel hilly course.

    4. Certifications

    NCE has the Japanese National Traffic Safety and Environment Laboratory (JNTSEL) certification to conduct testing for passenger car brakes (TRIAS 11-2-1994) and frontal crashes (TRIAS-47-1993). Manufacturers can contract to have NCE conduct their testing or contract with NCE to act on behalf of an official Japanese government witness for their in-house testing.

    **** Auto CAD

    We offer single source productivity to simplify the buying process and guarantee you have quality products, delivered on time. Newport Convertible Engineering (NCE) is on the cutting edge of technology. All designs are fully modeled in 3D to verify that all components will fit together the way they are planned. Directly from our design software (SolidWorks) the models are converted to the industry standard IGES file type, this file can then be directly imported into the Computer Aided Manufacturing (CAM) Software to build the parts. By eliminating the errors commonly associated with manual translation we can deliver higher quality products in record time.


    **** Dynamic Testing

    Newport Convertible Engineering (NCE) personnel, facilities and instrumentation provide you with the data you need to better understand your vehicle’s performance behavior.


    NCE safely accommodates your suspension, tire, brake and steering component testing. The facilities can be scheduled on a shared or exclusive basis and offer an ideal environment for dynamic comparison, development and performance testing.
