You can check out the basic specifications and pricing for the new 2007 Toyota Corolla in a previous post by clicking on the link. Toyota have made further information about the new Corolla available so sit back and do your best to absorb a little more info on the new ‘not so boring’ Corolla range.

Interestingly Australia is one of only a few markets in the world to see Toyota’s new 1.8-litre dual VVT-i engine in the Corolla. The new 100kW Toyota 2ZR-FE engine is the most powerful Corolla engine yet seen in Australia and is standard across the 2007 Corolla range.

The new engine is the only one in its class (VFACTS Small less than $40K) to offer variable valve timing technology with infinite adjustment on both the inlet and exhaust camshafts.

An engine capacity of 1.8-litres has been a Corolla standard for seven years now and it would appear that ‘the bar’ continues to be raised. The new dual VVT-i 2ZR-FE engine is a long-stroke version of the 1.6-litre 1ZR-FE engine offered in the Corolla hatch (Auris) in Europe.

The use of Toyota’s dual VVT-i system allows for optimum inlet and exhaust valve timing across the entire rev range resulting in torque being boosted in the low-to-medium engine speed ranges. Variable Valve Timing technology has previously provided most of it’s advantages at high engine rpm so it will be interesting to see just how flexible the new Corolla engine will be.

In a first for the Corolla, Toyota has made a 6-speed manual transmission standard across the range. The only exception being the Ultima sedan, which is only available with the 4-speed automatic. It is worth noting some of the more technical aspects of both transmissions as Toyota appears to have expended considerable effort on their design to ensure Corolla remains at the top of its class.

The 6-speed manual not only scores an extra ratio but special attention has been paid to achieving smooth shift feel and low shift lever effort, while a pre-load socket mechanism is used to suppress shift lever drifting. A pull-type collar is used to prevent the driver accidentally engaging reverse gear.

The C66 transmission has ratios of: first, 3.166; second, 1.904; third, 1.310; fourth, 0.969; fifth, 0.815; sixth, 0.725 and reverse, 3.250 and is matched to a 4.529:1 final drive ratio. Toyota claim that the ratios (note that 5th and 6th are both overdrive ratios) have been chosen to maximize both fuel efficiency and performance.

Toyota have used a three-point mounting at the front of the transaxle to reduce noise and vibration while the clutch has a new clutch plate structure to enhance wear resistance and reduce noise, vibration and harshness (NVH). The plunger-type clutch master cylinder is now made of resin to reduce weight…

Again, I find it odd that Toyota have continued with a 4-speed automatic instead of going for five or more but they claim it is better suited to the power and torque characteristics of the new engine…believe what you will. The 4-speed automatic is dubbed the U341E Super ECT and is electronically controlled with an ability to ‘read’ hills according to Toyota. This ability to sense the load experienced when driving up-hill allows the gearbox to reduce up-shifts under acceleration. In other words it will hold gears longer rather than up-shifting into a less appropriate gear. A five-speed automatic would still have been preferable.

The U341E Super ECT transmission has ratios of: first, 2.847; second, 1.552; third, 1.000; fourth, 0.700 and reverse, 2.343 and is matched to a 4.237:1 final drive ratio.

Toyota claim the following fuel economy figures for the 2007 Corolla:

Corolla hatch - ADR 81/01 fuel economy of 7.4 litres/100km* with manual transmission and 7.7 litres/100km* with automatic transmission.

Corolla sedan - ADR 81/01 fuel economy of 7.3 litres/100km* with manual transmission and 7.4 litres/100km* with automatic transmission.
