https://www.facebook.com/groups/Hyundaii10ClubTR Hyundai developed the second generation i10, which was originally planned for release in early 2014. Development of the new i10 started in India in 2012, using the Kia Picanto as a test mule for individual parts.[23] In August 2013, the i10's redesign was revealed by Hyundai's European design team led by Thomas Bürkle. The new car is 80 mm (3.1 in) longer, 65 mm (2.6 in) wider and 50 mm (2.0 in) lower than the outgoing model. The new dimensions result in a trunk space increase by 10%, totaling to 252 liters.[24] The new car made its debut at the 2013 Frankfurt Motor Show.[25] The i10 arrived in European showrooms in January 2014.[26] The engines offered on the European model will be as follows:[20] 1.0-liter three-cylinder petrol with 66 HP (48 kW) and 94 Nm (69 lb-ft) of torque 1.0-liter three-cylinder bi-fuel with 67 HP (49 kW) and 90 Nm (66 lb-ft) of torque (on LPG) 1.2-liter four-cylinder petrol with 87 HP (64 kW) and 120 Nm (88 lb-ft) of torque Production of the i10 commenced at Hyundai Assan Otomotiv's plant in İzmit, Turkey, in late-September 2013, at an annual capacity of 200,000 units.[27] The 1.0 litre three-cylinder engine makes 68 hp (51 kW; 69 PS) at 6,200 rpm and 70 lb·ft (95 N·m) of torque at 3,500 rpm. The engine block is made from high pressure die-cast aluminum which results in considerable weight savings - the entire engine with a manual gearbox only weighs 82.4 kg. The main block features a ladder frame construction for structural stiffness while its cylinders are fitted with cast-iron liners for improved abrasion durability. Additional weight was shaved off by integrating the engine support bracket with the timing chain cover. The shape of the piston skirt was optimized to reduce its size while the compression height of the piston was also reduced, resulting in weight savings. The optimized piston skirt is also treated with molybdenum disulfide. A highly sophisticated process of Physical Vapor Deposition (PVD) is used to apply an ultra-thin layer of Chromium Nitride to the piston’s oil ring. Chromium Nitride-coated piston rings using PVD is an innovative technology borrowed from the Hyundai Tau engine introduced earlier. Friction between the oil ring and cylinder wall has been further minimized by reducing the oil ring tension. The Kappa engine is the first Hyundai engine to be fitted with an accessory drive belt which does not require a mechanical auto-tensioning adjustment device, reducing the hardware and further lowering weight and cost. Because it is designed to maintain an ideal tension setting, the belt runs quieter and with proper preventative maintenance and care, the belt will last 100,000 mi/160,000 km. For ignition, the Kappa engine uses a new, longer reach spark plug which enabled engineers to enlarge the size of the water jacket to promote more efficient engine cooling around the critically important spark plug and exhaust port area. The long reach spark plug (M12 thread) also enabled engineers to enlarge the valve diameter for increased airflow and combustion efficiency. A lightweight, heat-resistant engineering plastic was used for the intake manifold. The fuel delivery pipe assembly is a returnless type (to eliminate evaporative fuel emissions) and is made of SUS (steel use stainless) with a specially designed inner structure for the reduction of pulsation noise. Hymermiling = Energy-efficient driving Energy-efficient driving techniques are used by drivers who wish to reduce their fuel consumption. Maintaining an efficient speed[edit] A truck restricted to 55 mph Maintaining an efficient speed is an important factor in fuel efficiency.[5] Optimal efficiency can be expected while cruising at a steady speed, at minimal throttle and with the transmission in the highest gear (see Choice of gear, below). The optimum speed varies with the type of vehicle, although it is usually reported to be between 35 mph (56 km/h) to 50 mph (80 km/h).[7][8][9] For instance a 2004 Chevrolet Impala had an optimum at 42 mph (70 km/h), and was within 15% of that from 29 to 57 mph (45 to 95 km/h).[8] At higher speeds wind resistance plays an increasing role in reducing energy efficiency. Road capacity affects speed and therefore fuel efficiency as well. Studies have shown speeds just above 45 mph (72 km/h) allow greatest throughput when roads are congested.[12] Individual drivers can improve their fuel efficiency and that of others by avoiding roads and times where traffic slows to below 45 mph (72 km/h). Communities can improve fuel efficiency by adopting speed limits[13] or policies to prevent or discourage drivers from entering traffic that is approaching the point where speeds are slowed below 45 mph (72 km/h). Congestion pricing is based on this principle; it raises the price of road access at times of higher usage, to prevent cars from entering traffic and lowering speeds below efficient levels.
