The size of an SUV significantly impacts its fuel efficiency; larger SUVs tend to have higher fuel consumption due to their greater weight and less aerodynamic shape. A full-size SUV might average 15-20 miles per gallon (mpg) (6.4-8.5 kilometers per liter (km/l)), while a compact SUV can achieve 20-30 mpg (8.5-12.8 km/l), offering a more economical ride due to their smaller engines and lighter frames.

SUVs, particularly those with all-wheel drive (AWD) or four-wheel drive (4WD) systems, are well-equipped to handle severe weather and rough terrain. Their higher ground clearance allows them to navigate through snow, mud, and uneven surfaces more effectively than lower-riding vehicles. Many also feature specialized traction control systems, robust suspensions, and off-road driving modes that enhance their capability in challenging conditions.

The sharing economy, through ride-sharing services, has disrupted the private transport industry by providing convenient, on-demand mobility options. It has reduced the need for personal vehicle ownership in urban areas and introduced competitive pressure on traditional taxi services, leading to a shift towards more flexible and often more cost-effective personal transport solutions.

Technology can enhance private transport efficiency via smart traffic management systems, real-time navigation to avoid congestion, and vehicle-to-vehicle communication to optimize flow. Additionally, developments in electric and autonomous vehicles can lead to more sustainable and self-regulating traffic systems, further reducing congestion and energy consumption.

General Motors is engaged in several partnerships, notably with Honda to develop electric vehicles and batteries. GM has also collaborated with LG Chem for battery production and with Cruise Automation for autonomous vehicle technology. Additionally, GM has partnerships aimed at expanding electric vehicle charging networks and advancing vehicle connectivity and data services.

General Motors' vehicles have shown mixed performance in reliability and consumer satisfaction, varying by model and year. Some models, like the Chevrolet Impala and Buick Encore, have received high marks for reliability. Overall, GM has been working to improve quality and customer service, and this is reflected in industry surveys and reports where certain GM brands have scored above average in consumer satisfaction. Continuous efforts in innovation and quality control are key aspects of GM's strategy to enhance vehicle reliability and customer approval ratings.
