Land Rover Noises: Does That Sound Right?
If you find it hard to discern where the noise is coming from, it probably means it's right underneath the vehicle and the sound is reflected from the road surface. Driving down a hedged lane or alongside a wall can help reflect the sound so you can hear it more clearly, but will mask its location. If the noise is from the engine, a mechanic's stethoscope can really help to identify the exact location when by touching different parts of the engine and listening for a change in the sound. When does it make the noise? Nine times out of ten the noise will come from a moving part and can be pinpointed to when that system is functioning. Is it noisy accelerating or decelerating? On idle, when you change gear, when you depress the clutch or turn the steering wheel? This can narrow it down to the vehicle system involved. What motion could create that noise? With the type of noise, you can help further identify systems involved from what its parts might be doing.
1,000. Which is great because I had to replace the rear brakes in 2017 and went right to Arrow. I called Arrow when my engine light and tire light went on after my last oil change and they suggested given my car is still under warranty (only 36,000 miles) that I take it to Land Rover. So, I made an appointment and dropped it off the night before. By 2pm the following day I hadn't heard anything so I called again, couldn't get a hold of Erik, had to wait for a call back. Someone else called me back to say they needed a part, that the warranty didn't cover overnight delivery but they could ship it up standard under the warranty. I said I'd prefer not to pay for the fact that they didn't stock the part my car needed. They told me I could come pick it up and drive it without doing damage to the car until the part arrived. I called ahead to let them know I was on my way.
But after spending a Martian year on the surface, which is 687 days on Earth, the Mars Curiosity rover has collected evidence of all the conditions necessary for microbial life within the rocks on the Red Planet. There are clues in the rocks pointing to a once wet, warm planet with lakes, rivers and deltas, a habitable environment where life could have evolved and thrived. When the planet transitioned to being a cold desert 3.5 billion years ago, that life most certainly disappeared. The new rover on the block wants to find that life and any other secrets hiding in the Martian rock and soil. It hasn't been named yet because NASA wants to open that honor to the public. Using the same platform as Curiosity, the new rover has a nuclear power source that can last at least 10 years, and has several cameras. Mastcam-Z, aptly located on the mast, can zoom like binoculars and create both panoramic and stereoscopic images, while also determining the mineral makeup of the Martian surface.
In this case, the electric torque boost provided by the Integrated Electric Rear Axle Drive significantly improves acceleration without adversely affecting either fuel consumption or CO2 emissions. The additional low-speed electric torque boost not only gives extra off-road ability, it also improves efficiency by using stored energy from the additional high-voltage battery system. Completely separate from the normal 12-volt battery system, this is a high capacity lithium-ion battery pack which is charged by regenerative braking energy. The regenerative braking puts otherwise wasted braking energy back into the high-voltage storage battery system. When slowing the vehicle, pressing the brake pedal causes the driveshafts and propshaft to transfer energy from the wheels to the Integrated Electric Rear Axle Drive system, decelerating the vehicle and transferring the 'braking' energy to the storage battery. For harder braking and for emergency stops, the conventional braking system is retained and fully operational, working in conjunction with the regenerative braking function.
