Restraints and dummy kinematics

Action shot taken during the frontal offset crash test.

The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained well.

Smeared greasepaint indicates where the dummy's head brushed the side airbag during rebound. The head also hit the roof, sunvisor, and grab handle before moving back against the head restraint.

Intrusion into the driver's space was minimal, and all leg and foot injury measures were low.

Tested vehicle: 2008 Infiinti EX35 Journey 4-door 4wd with standard front and rear head curtain airbags and standard front seat-mounted torso airbags

The Infiniti EX35 was introduced in the 2008 model year and renamed the EX37in the 2013 model year because the engine size was increased.

Two tests of 2008 EX35 models were conducted. The injury ratings for the driver are based on just the second test; measures for the driver in the first test were not obtained because of equipment failure. The injury ratings for the rear passenger and the head protection ratings for both the driver and passenger are based on both tests. Structural ratings also are based on both tests.

Tested vehicle: 2011 Infiniti EX35 Journey 4-door 4wd

Weighed one EX35 without Premium Package: curb wt using lift was 1806.0 kg (3981 lbs,) which gives SWR of 3.99. However when car was weighed outside on somewhat sloped ground, wt was 1794.5 kg (3956 lbs), which gives SWR of 4.01.

Joe said we've done due diligence, and let's contact Nissan to see if they can help us obtain car for weighing at the VRC under controlled conditions.

Nissan responded and provided the same vehicle at the VRC on 6/23/11. Four consecutive curb weight readings were obtained for a second 2011 Infiniti EX35 (VIN = JN1AJ0HR1BM852375, built Jan. 2011), this time without the optional Premium Package but with optional roof racks (made of aluminum alloy) and splash guards (not required). Floor mats, owner’s manual package, and license bracket/bolts were removed. Splash guards, protective plastic covers on all seats, and white plastic adhesive film on body sheet metal were not removed. The gas gauge was checked and it read above the “full” hash mark (photographed also). The donating dealer said the vehicle had not been driven since Andrew Brethwaite filled the tank a few weeks back. For each weighing, the car was driven onto the scales via ramps, rocked from side to side manually, weight recorded, and then backed off the ramps.

1. 1796.0 kg

2. 1801.0 kg

3. 1800.5 kg

4. 1800.5 kg

Even if we disregard the first reading, individual wheel weights and total weights are as follows:

Trial No. Left front Right front Left rear Right rear Total

2. 483.0 488.0 415.0 415.0 1801.0

3. 482.5 488.0 415.0 415.0 1800.5

4. 483.5 489.0 413.5 414.5 1800.5

Average 1800.7
