...new platform and changing dimensions...
Mercedes-Benz went the unconventional route and debuted their new GLA SUV completely online this morning. The new GLA comes on a new platform and changes up the dimensions a bit to improve interior space. Overall length is down 0.6 inches, but height has increased 4.1 inches, and wheelbase is up 1.1 inches while width is up 1.2 inches. This translates to some minor improvements in most, but not all, interior dimensions. (Dimensions chart on Page 2)
The GLA initially will come in three forms, the GLA 250, GLA 250 4Matic, and AMG GLA 35. The 250 and 250 4matic some with the same powertrain, a 2.0-liter turbocharged 4-cylinder producing 221 horsepower at 5,500 RPM and 258 lb-ft of torque at 1,620 - 4,000 RPM. Power is sent to the wheels via an 8-speed DCT.
The AMG GLA 35 comes with a 2.0-liter 4-cylinder with 302 horsepower at 5,800 RPM and 295 lb-ft of torque at 3,000 - 4,000 RPM. And uses a modified version of the 8-speed DCT. Zero to 60 is estimated at 5.0 seconds.
GLA 250 models equipped with 4Matic come with an Off-Road Engineering Package as standard. It is an extra drive mode that adapts the characteristics of the 4Matic system and changes power delivery and ABS intervention. The gauge cluster will present an animation of gradient, inclination angle, and technical settings to help the driver through the situation.
4Matic has been updated from being hydraulically activated to electro-mechanically activated. In normal mode, the system splits torque 80:20 front:rear. Sport mode changes that ratio to 70:30, while off-road mode moves it to 50:50. Being electro-mechanically operated allows the 4Matic system to be more efficient by not having to drive hydraulic pumps.
The GLA 250 is available with a host of driver assistance packages. They include:
Active Distance Assist DISTRONIC with the functions:
braking for stationary vehicles,
extended automatic restarting in traffic jams in conjunction with Active Parking Assist and navigation,
activation of "Gliding" in the ECO drive mode,
Active Steering Assist with the functions:
Active Emergency Braking Assist – with automatic unlocking and placement of an SOS call to the Mercedes-Benz emergency call center after the vehicle has come to a stop (depending on country)
Active Lane Change Assist in conjunction with navigation,
Emergency lane function: in freeway traffic jams at speeds below approx. 37 mph.
Active Speed Limit Assist with reaction to changes in speed limits in conjunction with Traffic Sign Assist,
Route-based speed adjustment when approaching bends, roundabouts, toll stations, T-junctions and before leaving highways – reduction of vehicle speed when encountering the end of a traffic jam, in conjunction with navigation,
Evasive Steering Assist,
Active Lane Keeping Assist,
Active Blind Spot Assist,
Active Brake Assist with cross-traffic function,
PRE-SAFE PLUS: can detect a potential rear impact. If the danger of a collision persists, the system can also firmly apply the brakes of the stationary vehicle, minimizing the risk of whiplash injuries by reducing the forward jolt caused by an impact from the rear.
The interior of the GLA is quite similar to the A-Class sedan. Mercedes MBUX is there and can be activated by voice simply by saying "Hey Mercedes".
AMG 35
The GLA AMG 35 gets an AMG tuned suspension, including an optional ride control system that allows the driver to select between three different drive modes. A high performance braking system with 13.8 inch disks up front and 13.0 inch disks in the rear is included. There is a speed-sensitive variable ratio steering that changes the amount of assistance offered at different speeds. The AMG also gets a special exhaust system with a gas flap to change the sound dynamics of the car depending on mode, engine speed, and engine load.
The exterior of the AMG GLA 35 gets a different front fascia from the regular GLA 250, fitting in with the rest of the AMG lineup.
The GLA 250 goes on sale Summer of 2020 with the AMG following after that.
