BEIJING, Feb 11 (Reuters) - Chinese electric vehicle

giant BYD this week began offering advanced autonomous driving

features on most of its models, including ones priced as low as

$9,555, a move likely to start a new price war in a

hyper-competitive market.

Below are what we know about smart driving features offered

in China, the world's largest auto market.

BYD

BYD described its proprietary God's Eye advanced

driver-assistance system as a three-tier platform segmented by

computing power.

The most affordable, entry level C version of the system

runs on models priced between 69,800 yuan ($9,500) and 219,800

yuan under BYD's best-selling Dynasty and Ocean series.

It supports automatic highway ramp exit and entry, lane

keeping, cruise driving, autonomous lane changes and obstacle

avoidance.

It also features autonomous emergency braking, self-parking

upon exit and remote parking.

The low-cost vision-only version, called God's Eye C system,

is equipped with 12 cameras, five-millimetre wave radars and 12

ultrasonic radars.

The system's two higher-end variations - God's Eye A and B -

run on BYD-branded cars priced from 219,800 yuan as well as its

premium Denza and Yangwang brands.

The two systems use advanced computing and lidars to

generate 3D images of a car's surroundings to assist navigation

around obstacles.

User access to such features is included in the sticker

prices.

TESLA

Tesla offers full self-driving (FSD) software for

subscription in China, but with a restricted set of features

that limits the system to operations, such as automated lane

changing.

Tesla vehicles offer basic autopilot features, including

traffic-aware cruise control and in-lane autosteer.

It charges 32,000 yuan for an enhanced autopilot assistance

suite that includes auto lane change and auto parking.

The FSD option for 64,000 yuan, which is expected to be

launched later this year, can recognise and respond to traffic

lights and stop signs and perform autonomous navigation on city

streets.

HUAWEI-BACKED AITO

The EV brand equips its best-selling car M7 with a pure

vision of Huawei's advanced driving system priced from 249,800

yuan.

Its basic version, which comes with three-millimetre radars,

10 cameras and 12 ultrasonic radars, features navigation on

highways and urban expressways, auto ramp entry/exit, partial

auto lane changes and obstacle avoidance, and smart parking.

The advanced lidar-powered version is used for the M7

variations priced at 289,800 yuan and allows navigation on city

streets and automatic emergency braking for special-shaped

obstacles.

For Huawei-backed other EV brands, including Changan's

Avatr, the advanced software is available for around $4,100 on a

subscription basis.

XPENG ( XPEV )

Xpeng ( XPEV ) launched its most affordable EV with advanced

autonomous driving features under its budget sub-brand MONA in

August.

The MONA M03 Max, which will be delivered later this year,

is priced from 155,800 yuan and features a vision-only solution

with lane-keeping control and adaptive cruise control,

navigation on highways and urban traffic, auto parking upon

departure and smart exit from parking spaces.

XIAOMI ( XIACF )

Xiaomi's ( XIACF ) smart driving system comes in two versions on its

SU7 EVs priced from 215,900 yuan, both featuring auto parking

and highway navigation.

The higher-end lidar-mounted version, as opposed to the pure

vision version, also enables urban navigation features such as

collision avoidance and special vehicle recognition on SU7 trims

priced above 245,900 yuan.
