Does the Teana have an anti-collision beam?
3 Answers
Teana is equipped with an anti-collision beam, which serves to transmit impact forces during severe collision accidents and protects the car body and some components from damage in minor collisions. The anti-collision steel beam is crucial for vehicles, though it is not a structural component; it is bolted to the car body. The Teana is a flagship mid-to-high-end luxury sedan under NISSAN, with body dimensions of 4868mm in length, 1830mm in width, and 1490mm in height, a wheelbase of 2775mm, a top speed of 210km/h, a minimum ground clearance of 135mm, and is powered by an inline 4-cylinder double overhead camshaft engine.
I've been driving the Teana for over a decade, and this car comes with both front and rear crash beams. Last time when my car got rear-ended, we found an aluminum alloy rear crash beam after removing the bumper - its deformation energy absorption worked quite well, and replacing it cost me around two thousand yuan. The thickness of crash beams differs between old and new Teana models, with the newer versions using more robust materials. Such midsize sedans generally come equipped with front and rear crash beams, but I must remind everyone: after minor collisions, it's best to check whether the beam has internal damage. If it's deformed, replace it promptly, otherwise it won't provide cushioning in the next collision. The Teana is quite decent in terms of safety features, after all, Nissan primarily targets the family car market.
As a veteran auto mechanic who has handled numerous Altima accident vehicles, I can confirm that both front and rear anti-collision beams come as standard equipment. However, there are two material types: older models used steel beams while newer high-end versions switched to lighter aluminum alloy beams. In terms of protection effectiveness, beam design matters more than material - the Altima's anti-collision beams feature well-engineered bending angles that effectively disperse impact forces during low-speed collisions. But be cautious with vehicles fitted with aftermarket bumpers, as some low-quality parts may obstruct the anti-collision beam screw holes. During routine car washes, you can feel behind the plastic bumpers - the anti-collision beams sit just about one centimeter behind that plastic layer.
