Rolls-Royce cars are the epitome of bespoke luxury automobiles. They can be completely custom crated or, for the more pedestrian buyer, they can simply be customized.

Before buyers place hands on the their new Rolls-Royce Phantom, the company has already tailored its audio system to create an encompassing audio experience for driver and passengers.

Unlike premium automakers who tout available systems from JBL, Bose, Harman Kardon, and B&O, Rolls-Royce prefers not to name its sound system suppliers, letting the system's engineering speak for itself.

It all starts with the car's frame. The Architecture of Luxury is made of aluminum, which was selected, in part, because it has a higher acoustic impedance than steel. This reduces the amount of noise that is passed on to the cabin. Engineers also gave the model a double-skinned bulkhead and floor sections to help keep road and tire noise permeation at bay.

Designers took note of the car's bass speaker size and let it define a resonance chamber in the car's sill section resulting in the car's materials working to turn the entire Phantom into, basically, a subwoofer.

The windows of the Phantom feature 6mm of double-pane acoustically dampened glass. It also has 130 kg of sound insulation throughout the car with a special focus on the headliner, designed to minimize reverberation.

Engineers even went so far as to work with their tire partner to invent "Silent-Seal" tires, which feature a layer of foam inside the rubber that reduces tire noise by 9 decibels compared to a standard tire.

Rolls-Royce audio experts drove thousands of miles in the Phantom before releasing it for public consumption. To determine the parameters in which to tune the system. Here's what they listened to:

  • From Here to Eternity – Giorgio Moroder, From Here to Eternity [1977]

Some owners have discovered that their car's video games work when the car is moving.

Tesla

Tesla's vehicles are among the most advanced and forward-thinking products of any kind, but serious innovation doesn't come with tradeoffs. The automaker has been in the news recently because of issues with how its advanced cruise control systems function, and now, Autoblog reports that the NHTSA is asking questions about Tesla giving drivers the ability to play video games and browse the internet while driving.

The feature is intended to be used while the car is parked, such as while charging, so the discovery that people can use them while driving is a serious one. Vince Patton, the person who filed the complaint with the NHTSA, tested his car and found that he could play Solitaire and a fairly involved action game while it was in motion. Internet browsing was also possible, meaning the driver could take their attention completely off the road ahead for extended periods of time.

Tesla Model 3Tesla's screens offer advanced functions that many others do not. Tesla

Tesla was already under investigation over crashes involving its Autopilot feature. Several collisions have occurred between Teslas and emergency vehicles stopped on the side of the road. Following the initiation of that investigation, the NHTSA raised other questions with the automaker over a buggy software update that was pushed out, retracted, fixed, and reissued outside of the normal recall process. Despite their names, it's important to clarify that neither the Autopilot nor Full Self-Driving features are capable of driving the cars without driver awareness and input.

Updated premium crossover

2022 Infiniti QX50 picks up new standard features

The new QX50 gets more tech and safety features.

Infiniti

Infiniti is one of a handful of automakers that have continued developing and building cars instead of focusing only on higher-profit and much more popular SUVs and trucks. That said, Infiniti's catalog is crossover- and SUV-heavy. Its smallest and least expensive crossover, the QX50 gets a handful of new features for 2022, and today Infiniti announced pricing.

Infiniti offers the 2022 QX50 in five trims: $40,025 Pure, $43,375 Luxe, $47,825 Essential, $52,525 Sensory, and $57,975 Autograph. All trims get Infiniti's variable compression (VC-Turbo) engine that makes 268 horsepower and returns up to 26 mpg combined. The advanced engine shifts its compression ratio to match the driver's behavior. When more power is needed, the compression changes, and when efficiency is the priority, it changes again. It's a marvel of engineering, but it's not as fuel-efficient as a hybrid. Power reaches the front or all four wheels through a continuously variable transmission.

2022 Infiniti QX50Pricing starts at around $40,000.Infiniti

Beyond the new standard features for 2022, buyers of the new QX50 will have to step up to the Luxe trim to get the most desirable features such as auto-folding exterior side mirrors, power lumbar support, and perforated leather upholstery. Standard comfort gear includes eight-way power front seats, dual-zone climate controls, a leather-wrapped steering wheel, and a Wi-Fi hotspot.

Infiniti stuck with its dual-screen infotainment configuration with the 2022 QX50. The top eight-inch screen handles wireless Apple CarPlay and Android Auto duties, as well as navigation. The bottom seven-inch screen handles vehicle controls, radio stations, and other settings. Though the system looks great and adds a high-tech feel to the cabin, two screens can be distracting and confusing while driving. The good news is that the QX50 gets an excellent 16-speaker Bose stereo starting with the Luxe trim.

The 2022 QX50 hasn't been crash tested by either major ratings organization yet, but the 2021 model performed well. It earned Good ratings in crash testes and a Superior score for its standard crash prevention systems. The 2022 QX50 comes standard with Infiniti's ProPilot Assist system, which brings advanced adaptive cruise control functions that can center the car in its lane, brake, and accelerate. Other standard tech includes blind spot monitoring, rear cross-traffic alerts, rear automatic braking, predictive forward collision warnings, and forward automatic emergency braking with pedestrian detection.
