Sentences with phrase «mechanical gear ratios»

The hybrid vehicles will use an electrically variable transmission (featuring two electric motors), two full hybrid modes of operation, and four fixed mechanical gear ratios.

Engine off at idle Low - speed, electric - only propulsion Cutting off fuel to the engine during vehicle deceleration Regenerative braking Energy - efficient accessory systems Unlike single - mode hybrid technology found in competitors» SUVs, the two - mode system maximizes city and highway fuel economy by integrating two electric continuously variable modes with four fixed mechanical gear ratios.

Having two mechanical gear ratios, controlled by clutches, does enable the power flow through the motor - generators to be kept small, but at considerable added expense in mechanical components.

With a single mechanical gear ratio, I'm not sure that's possible.

Not exact matches

The mechanical efficiency of this Getrag - built automatic has been a key contributor to the ability of the Focus to reach 40 mpg, but its unpredictable clutch engagement and frequent cycling of gear ratios could make you crazy.

The result is a riot with throttle response sharp enough to shave a peach, a truly fierce rush for the red line above 5500rpm, wonderful mechanical smoothness underscored by a crisp, snarling soundtrack, brilliantly - stacked gear ratios and arguably the slickest gearchange on the planet.

Changes include bonnet, roof, doors, boot lid and rear wings made from lightweight carbon fibre; carbonfibre reinforced plastic bumpers, wider front wings and rear diffuser; windows made from polycarbonate material, TRD driver's bucket seat, gear shift knob, ignition button and oil pressure and water temperature gauges; Momo steering wheel, Takata seatbelts, a TRD mechanical LSD replacing standard Torsen limited - slip differential, coil over suspension kit, final gear ratio shortened to 4.8:1, an oil cooler for the engine, a TRD mono block brake calliper kit with racing spec brake pads, TWS 18 - inch wheels with Yokohama Advan tyres, stock Toyota GT86 engine.

This is an SUV that can be had in the Rubicon model with heavy - duty Dana 44 axles with mechanical lockers, a 4:1 low - gear ratio, front and rear locking differentials, larger off - road tires, and an electronic disconnecting front sway bar that will allow your wheels to travel farther than ever when you tear up the rocks and trails you find around your Frankfort, IL home area.

GM chose to go the dual - mode route with 4 fixed gear ratio (instead of one fixed gear ratio as in direct mechanical coupling) in order to minimize load on the battery and for extended towing or pulling loads.

With two pure mechanical gear points, infinitely variable ratio in between, start - stop, regenerative braking, pure electrical mode, electric power assist, 100 % towing capability — the hybrid one seems to be better use of quite expensive planetary mechanics.

Another example is the limited - slip differential; the LT's is mechanical, with a 3.27 gear ratio.

In contrast, traditional mechanical transmission would change gear ratio to multiply torque.

The 850RE TorqueFlite automatic features a low 4.71:1 First gear and when paired with the Rubicon's NV241OR Rock Trac 4:1 (still with a manual shifter and mechanical linkage) delivers a JK - beating 77.2:1 crawl ratio (compared to 58.9:1 with the current five - speed automatic).

I would expect this transmission to have pretty comparable (and high) mechanical efficiency to the various DCT or manual transmissions, better than any CVT, and certainly better than old - style automatics (that had ratios too far apart to allow torque converter lockup except in top gear).

The automaker has also revised the 7 - speed DCT on the 2016 A45 AMG for shorter ratios in 3rd and 7th gear, while adding a new AMG Dynamic Plus package with a newly developed mechanical front axle locking to improve traction.

But the changes don't stop there — there have also been revisions made to the electronically - controlled four - speed automatic transmission (E-AT) to reduce mechanical losses, while the transmission lock - up range has been expanded in third and fourth gear during acceleration and steady - state running; lock - up has also been added to these ratios under deceleration.

Apart from the engine size, the only mechanical differences were: smaller front brakes, as the Juniors had not adopted the larger units fitted to the 1750 GTV and 2000 GTV from 1968 on, differential ratios (Junior models 4.55:1, 2000 GTV 4.1:1) and 5th gear ratio (GT 1300 Junior 0.85:1, all other Alfa Romeo 105 models 0.79:1).

Additional mechanical features include a rear limited slip differential with a 3.73 ratio gear, a maintenance - free battery with rundown protection and retained accessory power, Brembo brakes and a performance suspension with magnetic ride control.
