North American International Auto Show 2016: New cars launched at Detroit showcase

The 2016 North American International Auto Show opens on Saturday 16 January in Detroit. Around 45 new production vehicles and experimental concept cars are making their debut at the show.

Porsche is showing its new 911 Turbo and Turbo S models, with more horsepower, faster acceleration and higher top speeds. The 2017 911 Turbo and Turbo S promise 20 horsepower more than before and both have faster top track speeds — 7mph faster for the Turbo S, which now clocks in at 205 mph. Porsche says the heightened power and performance comes with increased fuel efficiency, but adds EPA ratings aren't yet available. The 911s go on sale in the US in April, with the Turbo starting at $159,200 (£110,000) and the Turbo S at $188,100 (£130,000).

Mercedes-Benz was the top-selling luxury brand in the US last year. The tenth generation of its E-Class sedan gets a new turbocharged, 2.0-litre four-cylinder petrol engine with 241 horsepower, up from 195 in the current diesel. Inside, the driver can control the "infotainment system" with smartphone-like swipes of a finger. Semi-autonomous driving capabilities including changing lanes by itself and maintaining a safe distance from the car in front at speeds of up to 130mph.

The new Lincoln Continental sedan is powered by a 3.0-litre twin-turbocharged V6 engine with 400 horsepower. It's targeted at customers in China, who have a particular appreciation for historic American brands. Lincoln expects to sell around 60% of the Continentals it makes in China. It has gently undulating sides, wraparound tail-lights and a panoramic glass roof. The doors open with very little effort and snap themselves closed, one of many ways designers tried to make the vehicle relaxing and serene. Inside, there are patented seats that can be adjusted up to 30 ways. They have separate settings for each thigh, inflating cushions, heating and cooling and a massage function, and they're designed to hug your back if you swivel around. In another nod to China, where many owners are chauffeured, there is a reclining seat in the rear. There's also a specially designed, 19-speaker Revel audio system.

A fuel cell concept car from Audi seeks to offer power and range with the convenience of quick refuelling. The h-tron quattro concept at the Detroit motor show is envisioned as a zero-emissions vehicle with power from electric motors in the front and rear. Audi says it will take four minutes to refill the tanks with hydrogen. Once the h-tron is fuelled up, its range will be nearly 373 miles. The new Audi A4 allroad quattro seeks to combine driving comfort with off-road performance. Available engines in the station wagon produce between 150 and 272 horsepower, up to 27hp higher than the previous model.

A fuel cell concept from Lexus is a "luxury fuel cell sedan of the future" says Akio Toyoda, chief branding officer and master test driver for Toyota's luxury brand. Toyoda says the goal for the LF-FC Concept, which could see production as soon as 2020, is to achieve a lot of zeroes: zero emissions, zero dependence on oil and zero accidents through advanced technology. Toyoda also unveiled the new LC 500, a sports performance coupe similar to the LF-LC Concept introduced at the Detroit show in 2012. The LC 500 offers a 5-litre V8 engine with 467 horsepower. It's expected to arrive in showrooms next year.

The BMW M2: The rear-wheel drive, high performance sports coupe offers a 3-litre, 6-cylinder engine producing 365 horsepower. BMW says it can go from 0-62 in 4.3 seconds and offers a top track speed of about 155mph. The German carmaker is also showing the X4 M40i.

Ford is adding performance to its midsize Fusion sedan lineup. The Fusion V6 Sport has a twin-turbocharged 2.7-litre EcoBoost V6 engine. It's expected to get 325 horsepower and 350 pound-feet of torque, about the same as the BMW 340i sedan and ahead of similarly equipped midsize cars from Toyota, Honda and Nissan. The V6 Sport has a unique black mesh grille, a rear spoiler and 19-inch wheels. A new pothole detection system can quickly adjust the shock absorbers to minimise the impact. There's also a new plug-in hybrid version of its Fusion

A hatchback version of the Chevrolet Cruze puts GM on equal footing with the Ford Focus and other compacts that come in hatch and sedan versions. The Cruze sedan debuts early this year, with the hatch coming out in the autumn. Both have a new 1.4-litre four-cylinder engine with stop-start technology that can get up to 40mpg on the highway. The problem for both: small cars aren't selling well in the SUV-crazy US.

Volvo's new luxury S90 sedan makes self-driving technology standard. The semi-autonomous Pilot Assist software allows the car to accelerate, decelerate, come to a complete stop and steer on a road with clear lane markings at speeds up to 80mph. Three engine choices will be available, including a four-cylinder, 2.0 litre turbocharged and supercharged engine and a plug-in hybrid.

Buick is showing the sleek, low-slung Avista coupe concept car with a mean-looking front grille, thin LED headlamps, 20-inch wheels and aggressive flared rear fenders. The Avista has a 400-horsepower twin-turbo V6 engine mated to an eight-speed automatic transmission. Buick says it will have the next generation of its "Quiet Tuning" suspension, advanced noise cancellation technology, air purifiers and even aroma therapy. Now, GM has to decide whether to build it – and where. Building the Envision crossover in China and shipping it to the US was a somewhat controversial decision by GM. The company GM says it wasn't economically feasible to build the Envision outside of China at current sales projections. GM expects to sell three quarters of them in China.

Hyundai is showing its Genesis G90 luxury sedan, which is available with either a 3.3-litre, twin-turbocharged V6 engine that offers 365 horsepower or a 5.0-litre V8 that packs 420 hp. All-wheel drive also is an option. Hyundai will tweak the G90 to best perform on the roads of the countries where it's sold.

Volkswagen hopes the next-generation Tiguan is the hit it needs in the SUV market. The concept version being shown in Detroit has a petrol-electric hybrid drive system and bolstered off-road performance. VW says the five-seat concept has two electric motors that boost total system horsepower to 221, pushing the SUV from zero to 60 in 6.4 seconds. The Tiguan concept will be able to go 20 miles in all-electric mode before the petrol engine comes on. It also has the latest safety features such as automatic emergency braking and pedestrian detection.

The Ford Raptor — introduced in 2009 — has been a hit among outdoor enthusiasts and those who like its brawny look. Now, the truck drops 500 pounds, making it faster and more agile, Ford says. There are six modes of driving, including a Baja mode for desert racing and a mud mode for mucky trails.
