The BMW i8 Concept retains much of the theatre and excitement of the BMW Vision EfficientDynamics concept that first previewed the futuristic sports car design at Frankfurt in 2009, and starred at the 2011 Australian International Motor Show in Melbourne last month. Sometimes it is time to leave the city. Escape the restrictions of everyday life. The BMW i8 is an icon of progress. It combines the energizing performance of a sports car with benchmark efficiency.

Unlike the Vision concept which utilised a diesel engine, the new 2014 BMW Sport Cars i8 Concept adopting a hybrid setup with an electric motor and a 1.5-liter gasoline unit. The 1.5-litre three-cylinder turbocharged petrol engine produces an astonishing 164kW of power and 300Nm of torque. To give that some perspective, the current BMW 125i is powered by a 3.0-litre inline-six with 160kW of power and 270Nm of torque – double the capacity, double the cylinders, 4kW less power, 30Nm less torque.

The 2014 BMW Sport Cars i8 Concept and the fascinating approach that underpins it embody the vision of a sustainable contemporary sports car brought to life. Its innovative plug-in hybrid concept combines the modified electric drive system from the BMW i3 Concept - fitted over its front axle - wîth a high-performance three-cylinder combustion engine producing 164 kW (220 hp)/300 Nm (221 lb-ft) at the rear.

The electric motor in the 2014 BMW Sport Cars i8 Concept is a full-capability unit which can also power the car on its own, if required. However, working in tandem allows the two drive systems to display their respective talents to the full, delivering the performance of a sports car but the fuel consumption of a small car.

Assisting the petrol engine is 96kW/250Nm electric motor, which draws power from a lithium-ion battery. With a combined maximum power output of 260kW and 550Nm, the i8 Concept is capable of accelerating from 0-100km/h in just 4.6 seconds (80-120km/h in 4.0 seconds) and will go on to an electronically limited top speed of 250km/h.

These impressive features of the German sports car are even greater considering that BMW announced a combined fuel consumption of only 2,7 liters/100 km. In terms of dimensions, the i8 Concept measures 4,6m long, 1,9m wide and 1,2m tall.

The great power amount offered by the new i8 is also valued by the low total mass of only 1,480 kilograms achieved by using a carbon fibre-reinforced plastic (CFRP) body and an aluminum chassis. The Germans claim that they managed to obtain a 50/50 weight distribution by mounting the engines on each axle, this achievement bringing significant advantages.

The weight of every component inside the 2014 BMW Sport Cars i8 Concept has been minimised down to the very last detail, allowing the extra weight of the electric drive system and battery to be cancelled out. The 2014 BMW Sport Cars i8 Concept therefore presents the ideal environment in which to sample this very special drive concept on the road. The passengers sit - in typical sports car style - in an extremely low and enclosed position inside the CFRP-constructed Life module (mounted above the Drive module).

“The sporting character continues into the interior. Boasting a driver-focused environment unmatched by any BMW Group vehicle before it, the 2014 BMW Sport Cars i8 Concept immerses the driver fully in the unique driving experience. The BMW i8 Concept is the sports car for a new generation – pure, emotional and sustainable,” adds BMW.

Far from just being a performance car, however, the i8 Concept can also be driven in fully electric zero-emissions mode for up to 35km. A full recharge of the battery from a standard power socket takes approximately 105 minutes.

The navigation system also calculates the best way to manage energy consumption for the trip to ensure that it operates at peak performance and optimal efficiency when required. Under the European driving cycle, the 2014 BMW Sport Cars i8 Concept uses fuel at a rate of just 2.7 litres/100km combined, making it one of the most fuel efficient internal combustion engined automobiles in history.

A production version of the BMW i8 Concept is expected to go on sale in Australia in 2014 with a predicted price tag of $300,000.

The design Kawasaki Sport Cars ZX-770R Hypercar Concept by Sabino Leerentveld based on Kawasaki bikes to rival the KTM  X-Bow, this is more hypercar level though as it would be 770HP, mid engine layout V6 twin turbo at around 5oo kilos.

The Kawasaki Sport Cars ZX-770R Hypercar Concept by Sabino Leerentveld design features a mid-mounted win turbo V6 capable of displacing 770 horses. The two-seater stands in at 1017mm high, 4427mm long and 2073mm wide with a wheelbase of 2710mm.

Weighing in at 500 kg, Kawasaki Sport Cars ZX-770R Hypercar Concept by Sabino Leerentveld sits pretty on 19 and 21-inch alloys with flowing curves smoothly overlapping to give it an overall semblance of a water stream galloping past rounded rock in Alpine rapids.

Although the designer’s vision was clearly inspired by the stallion-esque design of the iconic superbikes, the hypercar concept appears more fluent without that footnote undermining its crisp lines.

From entry-level 520d to flagship 507bhp M5, the BMW 5-Series never fails to impress – dynamically at least. In terms of styling, it’s a different matter. The kindest thing we can say is that the design has grown on us over time, although the bodywork remains clumsy and heavy-handed.Exactly the same criticism can be levelled at the driving environment. With its tall, slabby console and bulky binnacles, it’s the least attractive layout here. Worse still is the interior’s lack of stowage – there’s no handily accessible compartments on the transmission tunnel console.As a result, the BMW’s cockpit isn’t as welcom­ing as that in any opponent here. That’s a shame, because the driver is very well catered for. The seat is very comfortable and also the most supportive on test, with a spot-on position.Occupants in the back have plenty to be happy about, too, thanks to the well shaped, high-backed rear seats. And the 520-litre boot is generous.The engine is the best here for keen drivers – smooth and cultured, with minimal turbo lag and consistent power delivery across the rev range. But the 525d doesn’t perform any better than its riv­als, and the springy clutch action of the otherwise good six-speed manual box is hard work in traffic.BMW now seems to be getting to grips with run-flat tyres. The ride still isn’t as smooth as the Merc’s, but most ripples, ruts and ridges are dealt with well. The car’s sporty image means firm suspension, yet the handling makes this worthwhile. The 5 really enjoys being thrown into corners, and has the best steering feedback and body control.
