To ανανεωμένο Hyundai Veloster θα παρουσιαστεί μέσα στο 2015 και σύμφωνα με το The Korean Car Blog αυτό θα φορά τόσο ένα νέο 7-τάχυτο DCT κιβώτιο, όσο και το σύστημα διεύθυνσης Flex Steer. Το 7-τάχυτο αυτόματο κιβώτιο διπλού συμπλέκτη θα συνδυάζεται με τον 1.600αρη turbo κινητήρα, και θα αντικαταστήσει το τωρινό 6-τάχυτο. Το μοντέλο θα αποκτήσει νέο μπροστά προφυλακτήρα, νέα φωτιστικά σώματα, νέο πίσω προφυλακτήρα (με διαχύτη και κεντρικές απολήξεις εξατμίσεων στην Turbo έκδοση). Στο εσωτερικό θα συναντάμε νέα διακοσμητικά, νέο σύστημα ψυχαγωγίας και ενδεχομένως νέα καθίσματα στην Turbo έκδοση.
Στις σχετικές ειδήσεις, η Hyundai ανακοίνωσε ένα νέο 6-τάχυτο αυτόματο κιβώτιο για τα υβριδικά της μοντέλα. Το κιβώτιο ενσωματώνει τον ηλεκτροκινητήρα και θα πρωτοτοποθετηθεί στο Sonata. Με όλα τα μέρη του ηλεκτροκινητήρα να είναι τοποθετημένα μέσα στο κιβώτιο, ελαχιστοποιούνται οι απώλειες ενέργειας, αυξάνοντας την οικονομία καυσίμου. Το κιβώτιο ζυγίζει 130 κιλά, καθιστώντας το ελαφρύτερο από τη προηγούμενη έκδοση του, και αντέχει έως 280 Nm ροπής.

HYUNDAI MOTOR LAUNCHES MOTOR INTEGRATED SIX-SPEED TRANSMISSION FOR LATEST HYBRID MODELS
- New technologies within motor-integrated six-speed automatic will achieve an improved fuel economy of latest hybrid models
- High performance downsized 1.0-litre Kappa Turbo engine meets Euro6 standards
October 28, 2014 – Hyundai Motor has announced a new six-speed automatic transmission for hybrid electric vehicles (HEV) at the company’s annual International Powertrain Conference held today in Namyang, South Korea.
The new six-speed automatic transmission integrates the electric motor and applies a number of new technologies that deliver tangible benefits to the customer. The new unit will be fitted to future Hyundai hybrids, including the All-new Sonata.
The innovative set-up means that almost all of the hybrid powertrain components are contained within the transmission, minimizing energy losses and increasing fuel economy. A new traction motor and electric oil pump (EOP) have been fitted, while the torque converter has been removed completely. A lighter torsion damper, and new engine clutch, which features fewer clutch discs, reduce drag and contribute to a more efficient transfer and use of power.
The most significant change is within the oil pump system. The new transmission with the new oil pump system achieves improved fuel efficiency, by removing the mechanical oil pump (MOP) causing hydraulic losses and by applying a new electric oil pump (EOP) which automatically optimizes the system according to all driving conditions.
With fewer components, the new transmission weighs 130 kg (wet) – making it lighter than its previous version – yet still delivers 280 Nm (28.5 kg.m) of torque.
New 1.0-litre T-GDI
First displayed at the 2014 Paris Motor Show, the new Kappa 1.0-litre T-GDI is a high performance downsizing engine which could replace larger displacement natural-aspirated engines offering high fuel efficiency and low CO2 emission. The 998 cc three-cylinder unit is based on the established Kappa 1.0-litre MPI engine, carrying various enhancements and new technologies, including direct gasoline injection and a small, single-scroll turbocharger.
The 1.0-litre T-GDI engine produces 120PS (88.1kW) and peak torque of 17.5kgfm (172Nm) and will enhance Hyundai’s engine line-up in 2015.
The new engine comes with an electronically-controlled waste-gate to improve low-end torque and transient response with better fuel economy by reducing pumping friction. The unit features a six-hole laser-drilled GDI injector, high pressure fuel supply system of maximum 200 bar, securing clean combustion and improving fuel economy and emissions to fulfill Euro6 emission standards.
It uses a split-cooling concept to manage different temperatures in the cylinder head and block area. The cylinder block is heated up quickly for lower friction and more efficient run, while the cylinder head operates at moderately low temperatures to suppress knock tendency hence improve fuel economy. The exhaust manifold is integrated within the cylinder head which efficiently cool down the exhaust gas temperature using the cylinder head water jacket around the exhaust port. These efforts result in faster warm-up reducing real-world fuel consumption and emissions.
