modern era of automobile

The modern era is normally defined as the 25 years preceding the current year. However, there are some technical and design aspects that differentiate modern cars from antiques. Without considering the future of the car, the modern era has been one of increasing standardisation, platform sharing, and computer-aided design.

Some particularly notable advances in modern times are the widespread of front-wheel drive and all-wheel drive, the adoption of the diesel engine, and the ubiquity of fuel injection. While all of these advances were first attempted in earlier eras, they so dominate the market today that it is easy to overlook their significance. Nearly all modern passenger cars are front-wheel drive monocoque/unibody designs, with transversely-mounted engines, but this design was considered radical as late as the 1960s.

Body styles have changed as well in the modern era. Three types, the hatchback, sedan, and sport utility vehicle, dominate today's market,[citation needed] yet are relatively recent concepts. All originally emphasised practicality, but have mutated into today's high-powered luxury crossover SUV and sports wagon. The rise of pickup trucks in the United States, and SUVs worldwide has changed the face of motoring, with these "trucks" coming to command more than half of the world automobile market.

The modern era has also seen rapidly rising fuel efficiency and engine output. Once the automobile emissions concerns of the 1970s were conquered with computerised engine management systems, power began to rise rapidly. In the 1980s, a powerful sports car might have produced 200 horsepower (150 kW) – just 20 years later, average passenger cars have engines that powerful, and some performance models offer three times as much power.
