Frankfurt 2011: new avensis improved 2.0 d-4d and enhanced driving dynamics
Toyota Optimal Drive showcases a combination of wide-ranging advanced technologies and internal improvement programmes designed to optimise the balance of performance and driving enjoyment with fuel economy and low emissions.
These diverse core technologies focus on three key aspects of powertrain development: Firstly, the reduction of powertrain weight through the use of super-lightweight and highly compact engine components and transmissions secondly, the minimisation of mechanical losses through the reduction of friction throughout the drivetrain and, thirdly, the maximisation of combustion efficiency.
The 124 hp 2.0 litre D-4D turbodiesel has been extensively revised. The unit features a new turbocharger, extensive combustion chamber modifications and improved glow control. As a result, torque delivery has become more linear, fuel efficiency has improved and CO2 emissions have been lowered by some 15% -from 139 to only 119 g/km- in both sedan and wagon versions of the new Avensis.
This marked reduction in CO2 emissions has significant Total Cost of Ownership implications. A taxation threshold of 120 g/km exists in almost a third of all European countries, and the revised 2.0 D-4D unit's 119 g/km CO2 figure offers tax benefits for both private and fleet drivers.
In addition to the revised 124 hp 2.0 D-4D turbodiesel, the new Avensis' six powertrain range further comprises a 150 hp, 2.2 D-4D unit available with either a Diesel Particulate Filter (DPF) or a Diesel Particulate and NOX Reduction filter (DPNR), a 177 hp 2.2 D-4D DPNR variant, and a choice of 132 hp 1.6 litre, 147 hp 1.8 litre and 152 hp 2.0 litre petrol engines.
All engines are mated to 6-speed manual transmissions. The 150 hp 2.2 D-4D DPNR unit may be optionally equipped with a 6-speed automatic transmission, and both 1.8 and 2.0 litre petrol engines may be fitted with Toyota's Multidrive S continuously variable transmission with steering wheel mounted paddle shift.
The new Avensis retains the same proven front McPherson strut and rear double wishbone suspension layout of its predecessor. However, platform, chassis and powertrain improvements offergreater ride comfort and enhanced handling agility, promising a more engaging driving experience.
The new Avensis also benefits from enhanced Noise, Vibration and Harshness (NVH) suppression. Extensive insulation modification, and improved dashboard inner silencer and a new, sound-absorbing carpet helping to deliver a quieter, more refined cabin environment.
